Walmart bikes may seem OK, they're not, they're not OK,they are definately not good.Fatal flwas have rendered them unacceptable for LBS's to sell, buy and large.Anyway, if you have a problem, then what?
People that work at w.mart don't even know where to find stuff they sell.Some will say "why not, just return it if you don't..." I say,"why bike anything based on returning it".Target is better if you know what to avoid.If you absolutely ,possitivly, must go the cheap route, try a large sporting goods store: Dick's,Ski Barn,Curry's, you know a big sporting goods store that even sells bowling balls and rain jackets and tents. eemmmkkkaaaayyyy
