Mary O's Exxon: A Neighborhood Grocery and Gas Stop in Columbia

What Mary O's Exxon offers

Mary O's Exxon is a combination gas station and convenience grocery in Columbia that serves the immediate neighborhood with fuel, everyday groceries, and prepared food. The station operates as a small-format market attached to an Exxon pump, stocking basics like milk, bread, canned goods, and snacks alongside the fuel pumps. It's the kind of place where locals stop for a quick errand rather than a full shopping trip—grab gas, pick up a few items for dinner, maybe grab a sandwich or hot food if you're in a hurry.

The store's real draw for many Columbia residents is convenience and familiarity. You're not navigating a sprawling supermarket layout; you're in and out. The prepared food counter makes it useful if you need lunch or a quick dinner without leaving the neighborhood, and the gas pumps mean you can handle two errands at once.

Where to find Mary O's Exxon in Columbia

Mary O's Exxon is located in Columbia's midtown area, accessible by car from most neighborhoods in the city. The address and exact location can shift over time, so calling ahead or checking current maps before your first visit will save you time. The station sits on a main road with easy pump access and a small parking area for the convenience store.

If you're already in the neighborhood running other errands, Mary O's is worth knowing about as a backup option for groceries or a quick meal. It's not a destination store—most people find it because they live or work nearby.

What you can buy at the prepared food counter

The prepared food section typically includes hot sandwiches, which are made fresh during operating hours. The menu and availability depend on the day and time you visit, so what's available at 7 a.m. may differ from what's ready at 5 p.m. The sandwiches are priced for quick lunch or dinner, not as a budget option compared to cooking at home, but they're faster than waiting for delivery.

Beyond sandwiches, the counter may stock other hot items depending on the day. Calling ahead if you're counting on a specific item is a smart move, especially during slower hours when the counter might not be fully stocked.

Grocery items and everyday supplies

The convenience grocery section carries the basics you'd expect: milk, bread, eggs, butter, canned vegetables, pasta, cereal, and snacks. The selection is limited compared to a full supermarket—you won't find specialty items or a wide range of brands—but it covers the most common things people run out of between bigger shopping trips. Prices tend to run higher than a large grocery chain because of the smaller format and neighborhood convenience factor.

The store also stocks drinks, coffee, and other beverages. If you're looking for a specific brand or product, calling ahead is worth the minute it takes, since inventory in small convenience stores can vary week to week.

Gas and fuel services

Mary O's Exxon operates as a full Exxon fuel station with multiple pumps. You can pay at the pump with a credit or debit card, or inside at the counter. The fuel prices track with other Exxon locations and change daily based on the market. If you have an Exxon rewards program or credit card, you can use those at the pumps to earn points or get discounts.

The station is open during standard hours for a neighborhood convenience stop, though exact hours should be confirmed by phone or online before planning a late-night or early-morning visit.

When to shop at Mary O's versus a larger grocery store

Mary O's works best when you need one or two items quickly and you're already in the area, or when you're filling up gas and want to grab milk or bread at the same time. It's not the place to do a full weekly shop—prices are higher, selection is smaller, and you'll spend more overall than at a supermarket like Food Lion or Harris Teeter.

If you live or work within a few blocks, Mary O's is valuable as a backup for forgotten items or a quick lunch. If you're driving across town specifically to shop for groceries, a larger store will give you better prices and more choice. The real value is neighborhood convenience, not savings.

Frequently Asked Questions

What are the hours at Mary O's Exxon?

Hours vary, but most neighborhood convenience stations operate from early morning through evening. Call ahead or check online to confirm the exact hours before your visit, especially if you're planning to stop by early or late in the day.

Can I use my rewards card or credit card at the pumps?

Yes, you can pay at the pump with a credit or debit card. If you have an Exxon rewards program or Exxon credit card, you can use those to earn points or discounts on fuel. Ask inside if you're unsure how to activate rewards at the pump.

Is Mary O's Exxon a good place to do my weekly grocery shopping?

No—prices are higher than supermarkets and the selection is limited to basics and convenience items. It's best for quick trips or one or two forgotten items. For full weekly shopping, a larger grocery store will save you money and give you more options.

What if I can't find what I'm looking for?
