I don't know what store the 1 star reviewer went into, but it obviously wasn't the one in Tupelo. I've been shopping there a lot lately and it is extremely clean and well-organized. The inventory changes constantly and I'm addicted to going back to see what bargains have arrived each week. I signed up for the In the Loop club to get emails sent to me about new stock and now I can go to wallsbargaincenter.com and look at the individual store's webpage for a list of new items they've gotten in.
All in all, a great store. Like any other store though, some things are bargains and some are not, you just have to know what you are buying and be familiar with the prices. Chances are if an item in the store is too high this week, it'll go down soon enough and you can get it at a bargain price sooner or later.
