Walmart "Supercenter" 1295 is a horrible WalMart in a Horrible town in a horrible state. The state has a grocery tax on groceries and Madill is 9%. This is a very tiny WalMart, despite its "SuperCenter" upgrade in late August 2009. It is so tiny and there is not any Self Checkouts. The cashiers are dumb and if they make a mistake or if they just don't like you they are all very rude and will call CSM and they are on the verge of calling the police. (VERY Common in a ma and pa store, and this IS a Ma and Pa store's atmosphere, despite it being "WalMart") I mean they are VERY rude. This tiny Walmart is cramped and usually does not have what you need. I do NOT have the time to go somewhere only for the store to NOT have it. Milk is expensive in Oklahoma and very much so with Madill WalMart. Braum's has less expensive milk. Food costs MORE than gas so I recommend that you just shop in a better Walmart If you are in Southeastern Oklahoma, there are Walmarts such as Durant. Or "Dew Rant", home of "World's Largest Peanut", "Historic" Downtown, Southeastern Oklahoma State University (aka "The College"), and the Choctaw Casino "Resort". Sales Tax there is 9.125% and this supercenter has irregularly placed strip malls around it and the supercenter is dangerously close to the Kiamichi Railroad. Ardmore Walmart is a nice Walmart that is IN a strip mall, and has VERY cramped parking. So just go to Texas. Hugest Walmart Around is Gainesville. Runner Up is Sherman and Second Runner Up is Denison. Just go there instead. read more
