What You'll Find Inside

Uncle Sam Mart stocks the standard convenience store items: soft drinks, coffee, snacks, candy, and packaged foods. Many locations carry regional brands and products that reflect South Carolina preferences, alongside national brands. If you are looking for a specific item, calling the store directly is faster than guessing whether they carry it.

Beyond snacks and beverages, stores typically offer basic necessities like ice, lottery tickets, and sometimes prepared food items. The selection and specific offerings can differ between locations, particularly between high-traffic stores and smaller neighborhood stops. Some locations may carry items like automotive supplies or cleaning products, but this varies.

Fuel Services and Payment Options

Most Uncle Sam Mart locations include a fuel station where you can purchase gasoline. Payment at the pump is standard, and you can typically pay with credit cards, debit cards, or cash. Inside the store, all major payment methods are accepted, though some older locations may have minimum purchase requirements for card payments—a practice that is becoming less common.

Fuel prices at Uncle Sam Mart follow market rates like other independent stations, so prices may differ slightly from major national chains depending on the location and current market conditions. If you are a frequent customer, asking about loyalty programs or rewards at your local store is worth doing, as some locations offer them.

Loyalty Programs and Specials

Some Uncle Sam Mart locations offer customer loyalty programs or periodic specials, though these vary by store. The best way to learn what your nearest location offers is to ask staff when you visit or call ahead. Unlike large national chains with uniform programs, Uncle Sam Mart's approach to rewards and promotions can differ between stores.

Checking with individual locations about fuel discounts, beverage specials, or rewards programs ensures you know what savings might be available to you. Social media pages for specific stores sometimes announce local promotions, so following your nearest location online can keep you informed.

Hours and Services by Location

Uncle Sam Mart store hours vary significantly depending on the location. Some stores operate 24 hours, while others close in the evening or have limited weekend hours. The only reliable way to know your nearest store's hours is to contact them directly or check their online listing.

Services also differ by location—some stores may have restrooms, ATMs, or additional amenities, while smaller locations may not. If you need a specific service, calling ahead prevents disappointment. Many locations post their hours and services on Google Business or their own websites, which you can check before visiting.
