Where Walmart Clusters in South Carolina: How Store Density Shapes Everyday Shopping

If you shop the Grand Strand, you already feel it. Within a few minutes of 38th Avenue North and Kings Highway in Myrtle Beach, there are four Walmarts you can hit before lunch. The Myrtle Beach N Kings Hwy 38th Ave Neighborhood Market at 3915 N Kings Hwy posts daily 6 am–11 pm hours and lists a pharmacy window of 9 am–7 pm Mon–Sat and 10 am–6 pm Sun. One mile inland, the Seaboard St Supercenter at 541 Seaboard St runs the same 6 am–11 pm schedule with its Auto Care Center open until 7 pm. A few miles south, the Walton Drive Neighborhood Market at Market Common and a second Neighborhood Market on S Kings Hwy round out an ultra-short hop between four formats. That’s density you can plan a full grocery, pharmacy and car errand loop around without crossing town.

Not every South Carolina metro is packed that tightly, but the pattern repeats. Across the Upstate, Midlands and Lowcountry, Walmart’s footprint follows the interstates and the main suburban arterials. The effect isn’t just convenience. It decides where curbside pickup is quickest, which pharmacy closes soonest, and how often you really need a separate warehouse-club membership for bulk buys and fuel. The specifics below focus on the places and hours that actually drive your decision on a Saturday morning.

Grand Strand concentration around US 17: Myrtle Beach’s cluster versus one big-box magnet

Start with Myrtle Beach proper, where three Walmarts sit within roughly four miles of each other. The Neighborhood Market at 3915 N Kings Hwy is daily 6 am–11 pm, and it flags sensory-friendly hours from 8 am–10 am each day. The pharmacy drive-thru lists 9 am–7 pm Mon–Sat and 10 am–6 pm Sun, which matters if you’re timing refills around the beach traffic. The Seaboard St Supercenter also holds a 6 am–11 pm store day, with its pharmacy open from the morning and the Auto Care Center scheduled through the early evening at 7 pm.

That density tilts everyday errands toward Walmart even with a warehouse club nearby. Costco Myrtle Beach at 1021 Oak Forest Ln runs Gold Star shopping hours of 10 am–8:30 pm weekdays, 9:30 am–7 pm Saturday, and 10 am–6 pm Sunday. Executive Members can start at 9 am on weekdays, and the gas station posts early openings at 6 am most days. If your list is bulk meat, tires and a rotisserie chicken, Costco is a single stop. If you also need a same-day prescription and an oil change, the Walmart cluster along Kings Hwy and Seaboard St often wins on timing and proximity.

Drive inland toward Conway and the pattern is a lighter version of the same thing. The Conway Supercenter at 151 Myrtle Ridge Dr covers the west side with grocery, general merchandise and curbside pickup, while the Church St Supercenter on the north side catches travelers headed to 501. You still get the statewide Walmart baseline of 6 am–11 pm most days, plus the now-standard sensory-friendly 8 am–10 am window. For beach renters and seasonal workers, it means you can shift runs between resort-area stores and inland options without relearning hours each time.

Upstate reality along I‑85: Greenville’s overlapping choices and a mall that still draws its own trip

The Upstate isn’t as hyper-compact as the Grand Strand, but Greenville’s options still stack close. The Greenville Pelham Rd Supercenter at 3925 Pelham Rd opens at 6 am and closes at 11 pm. Its Vision Center lists an opening at 9 am, and the nearby Taylors Supercenter on Wade Hampton Blvd shows the same 6 am–11 pm rhythm. Cross-town on US‑25, the White Horse Rd Supercenter runs a matching 6 am–11 pm day with an Auto Care Center posted through the evening and a pharmacy operating into the early night.

Greenville’s Neighborhood Markets fill the in-between. The Old Buncombe Rd Neighborhood Market at 5009 Old Buncombe Rd also runs 6 am–11 pm daily, with a pharmacy drive-thru listed at 9 am–7 pm Mon–Sat and 10 am–4 pm Sun. Its on-site fuel station keeps earlier hours, closing at 8 pm, which is useful if you want to get a grocery run and fill-up done before dark without jumping to a larger Supercenter.

If you plan a full shopping day around fashion and specialty stores, Haywood Mall at 700 Haywood Rd remains the Upstate’s indoor anchor. The mall’s regular hours run 10 am–8 pm Mon–Thu, 10 am–9 pm Fri–Sat, and 12 pm–6 pm Sun. From there, two Supercenters bracket your route for practical add-ons. Walmart at 1451 Woodruff Rd shows 6 am–11 pm and handles busy weekend traffic off I‑385, while the Pelham Rd Supercenter on the east side opens its pharmacy at 9 am for morning refills. In practice, you can grab shoes at Haywood Mall at 10, pick a prescription by 11, and still be back across Woodruff Rd for curbside pickup before noon.

Midlands map: Columbia’s rings on I‑20 and I‑77

Columbia’s Walmart density reads like concentric rings. To the northeast, the Killian Rd Supercenter at 321 Killian Rd serves the I‑77 growth corridor with curbside and a full general-merchandise set. Across Forest Acres, the Forest Dr Supercenter at 5420 Forest Dr carries the same open-to-close pattern and is the closest big-box pharmacy for neighborhoods east of downtown. West through St. Andrews and Harbison, you get several more choices including West Columbia’s Supercenter at 2401 Augusta Rd, which holds to the statewide 6 am–11 pm day and bundles auto, pharmacy, and grocery under one roof.

Columbia is also where the local warehouse-club math really shows up. Sam’s Club Columbia Harbison at 350 Harbison Blvd posts 9 am–8 pm daily club hours and a 8 am–9 am early shopping hour for Plus members. The fuel station at that address runs later into the evening, posted to 10 pm, and the in-club Auto & Tires department shows a 7 pm close. If you regularly buy bulk and want early access, those hours can tilt you to Sam’s on a weeknight. If you need a 7:30 am start or a late pharmacy window on Sunday, the ring of Walmarts wins.

Lowcountry spread: Charleston’s big boxes where the interstates meet

Charleston’s Walmarts spread along the interstates and suburban arterials rather than stacking in a single district. North Charleston’s Rivers Ave Supercenter at 7400 Rivers Ave and the Centre Pointe Dr Supercenter at 4920 Centre Pointe Dr serve I‑26 and I‑526 traffic. The Rivers Ave store runs 6 am–11 pm with both grocery and general merchandise under one roof, and its shopping-services page is built around curbside and delivery for commuters heading to and from Summerville or Goose Creek.

West Ashley shoppers use the W Ashley Cir Supercenter at 3951 W Ashley Cir for the same 6 am–11 pm rhythm. If you are pairing a Walmart run with a warehouse-club fill-up in the same area, Sam’s Club North Charleston at 4900 Centre Pointe Dr posts general club hours of 9 am–8 pm daily and a fuel station that opens at 6 am. That early gas hour is one of the few places a club membership changes your morning routine more than Walmart’s own fuel stations, which often post earlier closes than the club pumps.

Formats, hours and memberships: what actually changes your errand math

Walmart’s statewide pattern is consistency with just enough local variation to matter. Most Supercenters and Neighborhood Markets list 6 am–11 pm daily store hours, plus the chain’s sensory-friendly window of 8 am–10 am each day. Pharmacies run shorter days. The Myrtle Beach N Kings Hwy pharmacy shows 9 am–7 pm Mon–Sat and 10 am–6 pm Sun, while Greenville’s Old Buncombe Rd pharmacy posts 9 am–7 pm Mon–Sat and a shorter 10 am–4 pm Sun. Auto Care Centers commonly close at 7 pm in larger Supercenters such as Seaboard St in Myrtle Beach and Dorman Centre Dr in Spartanburg, which helps if you plan an early evening oil change after work.

Memberships are where the alternatives diverge. Walmart+ is $98 per year, and it extends free shipping with no order minimum, same-day grocery delivery from stores in many zip codes and member fuel discounts at Walmart, Murphy and Sam’s Club stations. Costco lists a $65 Gold Star and $130 Executive fee tier, with Executive Member weekday entry starting at 9 am in Myrtle Beach. Sam’s Club operates on standard and Plus tiers as well, and Plus membership unlocks 8 am–9 am early shopping daily and expanded shipping perks. If you only need curbside pickup, Walmart’s non-member option already gets you fast fulfillment windows from neighborhood stores in populated corridors. If you want early entry and club-only tire, optical or hearing services, those membership hours and on-site departments at Harbison and Centre Pointe may be decisive.

How to use the density in each region

Myrtle Beach

Stack small tasks in a tight loop. Start at the N Kings Hwy Neighborhood Market when the doors open at 6 am, then hop to Seaboard St for Auto Care by 7 am. If your list includes bulk paper goods or tires, divert to Costco at 10 am Gold Star opening or 9 am if you carry Executive. You can still swing back for a pharmacy drive‑thru refill at Kings Hwy before the 7 pm Saturday close.

Greenville

Anchor discretionary shopping at Haywood Mall in the late morning. Pair that with a midday curbside pickup at 1451 Woodruff Rd or a fast pharmacy visit at 3925 Pelham Rd when its Vision Center opens at 9 am. If you live northwest, the Old Buncombe Rd Neighborhood Market can be your fuel and grocery stop in one, with its fuel station closing at 8 pm.

Columbia

Use the ring. If you commute up I‑77, load curbside pickup at Killian Rd where the Supercenter posts early 6 am openings. If you want Plus early hours and late gas, Sam’s Club Harbison hands you 8–9 am entry and a pump posted to 10 pm. The practical play is Walmart for groceries and pharmacy windows, Sam’s for bulk and fuel on nights and Sundays.

Charleston

North Charleston’s two Supercenters split the loads of I‑26 and I‑526, so pickup windows tend to be available even on busy weekends. Rivers Ave runs 6 am–11 pm and supports curbside for commuters from Ladson and Goose Creek. If you also need club-only items or cheaper fuel before sunrise, Sam’s Club Centre Pointe posts a 6 am fuel start and 9 am club opening.

Key things to know before you plan your route

• Most South Carolina Walmarts list 6 am–11 pm daily hours, with chainwide sensory-friendly shopping from 8 am–10 am.
• Pharmacy windows are shorter. Example: 3915 N Kings Hwy, Myrtle Beach posts 9 am–7 pm Mon–Sat and 10 am–6 pm Sun, while 5009 Old Buncombe Rd, Greenville shows 9 am–7 pm Mon–Sat and 10 am–4 pm Sun.
• Auto Care Centers at larger Supercenters commonly close at 7 pm. Plan oil changes or tire rotations before the dinner hour.
• Walmart+ runs $98/year. If you already rely on curbside or delivery and buy fuel at Walmart or Murphy, the member benefits stack with the Walmart density you have nearby.
• Costco Myrtle Beach consolidates bulk and tire service but has stricter hours. Gold Star opens at 10 am on weekdays, Executive at 9 am, and its pharmacy is closed on Sundays.
• Sam’s Club Harbison and North Charleston list 8–9 am Plus early shopping and later fuel hours, useful if you want a club stop outside Walmart’s pharmacy window.
• When you need multiple stops in one trip, use micro-clusters. Around Kings Hwy and Seaboard St in Myrtle Beach, you can hit four Walmart locations within a few miles, all running to 11 pm.

Reader Q&A

Where in Myrtle Beach can I hit Walmart, pharmacy and auto care without crossing town?

Base yourself near 38th Ave N and Kings Hwy. The Neighborhood Market at 3915 N Kings Hwy runs 6 am–11 pm with a pharmacy to 7 pm on weekdays, and the Seaboard St Supercenter is roughly a mile away with Auto Care posted to 7 pm. Two more Neighborhood Markets sit a few miles south for backup curbside slots.

Does Greenville still have a mall day worth planning around, or is it all strip centers and Supercenters?

Haywood Mall still draws a dedicated trip with regular hours of 10 am–8 pm Mon–Thu, later on weekends. From there, Walmart 1451 Woodruff Rd and 3925 Pelham Rd both run 6 am–11 pm, so you can add curbside pickup or a pharmacy visit without stretching the day.

How do Walmart hours compare to Costco and Sam’s Club if I’m choosing a membership?

Most Walmarts post 6 am–11 pm daily with shorter pharmacy windows. Costco Myrtle Beach opens to Gold Star at 10 am weekdays and is closed Sundays in the pharmacy. Sam’s Club lists 9 am–8 pm club hours with 8–9 am Plus early entry. If you need earlier mornings or later gas, Sam’s Club wins; if you need a later pharmacy seven days a week, Walmart’s footprint wins.

Is Walmart+ worth it in South Carolina if I already shop in person?

If you use curbside or delivery often, Walmart+ at $98/year pairs well with the dense network in the Upstate, Midlands and Grand Strand. The added fuel discount and free shipping are easiest to realize around clusters like Myrtle Beach or Greenville where pickup windows are plentiful.

To narrow your choice, start with your pharmacy and auto-care timing. If a later pharmacy window and a 7 pm oil-change slot matter, the nearest Supercenter or Neighborhood Market will usually beat a club stop. If you buy bulk monthly and want 8–9 am early entry or earlier gas, add a Sam’s or Costco membership to the same route.
