Willie's Supermarket is a supermarket owned by Bill Binder, and located off Procopio Drive and Paleto Boulevard in Paleto Bay, Blaine County. The business has a wide variety of products such as pharmacy products and firearms.
The store boasts a twenty-two-space parking lot, with a rectangular grass island. Four wooden benches line the front of the building and various advertisements are pinned up on the windows. Although unenterable, cardboard boxes of Sprunk and numerous aisles can be seen inside.
- The title in one of the i's is missing a bulb and one of the r's in 'Supermarket' is not present. Thus, the sign's actual string of letters, excluding the burnt out and missing ones, is 'Will e's Supe market'.
- The ability to purchase firearms is probably a reference to the American supermarket chain Meijers, which has a grocery and a sporting goods section.
- The most common vehicle to spawn in the parking lot is the Dundreary Regina.
