Can I return my iTouch to Walmart?

Can I return iPod to Walmart if I do this?

• I bought an iPod touch 4th gen 64gb for 421 with tax a week ago, now having looked at newegg's price I want to return it and save liek 70 dollars but here's what I want to do: Buy Newegg's ipod touch 4th gen with 64gb and put this one in the case that carried the Walmart's ipod touch so that I can keep the scratched ipod (walmart's) and give walmart the new one (newegg's). HOWEVER, newegg's ipod model is MC547LL/A, Walmart's model is A1367. WILL I GET IN TROUBLE OR SOMETHING IF I DO THIS? TL;DR: Bought Walmart's iPod. Want to return to buy cheaper. Before returning buy Newegg's different model iPod, put it in Walmart iPod's case and then return. Ok to do this or should I give Walmart their iPod back with the scratches?

• Answer:

  You bought an iPod at $421. Why did you keep looking for a lower price? WalMart will "match" the price, but, come on, it isn't a lifetime price guarantee. If you wanted tomorrow's price, you should wait until tomorrow to buy it.
