It's not return fraud if you bought a copy at MSRP at Gamestop and returned a sealed copy at the same store, regardless of where you got that copy from. You're simply returning the same product they gave you for the same amount you paid for it originally.[/QUOTE]
It's mild return fraud. Most stores, if they knew, wouldn't be too pleased with being treated like a cost-free rental shop becuase you didn't feel like waiting for shipping (and would probably ask why you didn't buy from them in the first place- "we didn't make you wait!")
However, the store isn't going to know, becuase you're returning exactly what you bought. (You cashier may be annoyed and wonder why you wasted your time/money and theirs.)
It's not a big deal- but why so impaitent, anyway? I'm sure you've got other games to play for a week or so.
