Question about Best Buy's Ocarina of Time deal

[Lazer77]

Its if you buy Ocarina of Time and any other 3DS game, you will get a $25 gift card.

Now lets say I buy OOT and any cheap game (cheapest is $25 I believe), and get my gift card. If I came back later that afternoon and tried to return the second game, and make up some lie like I didn't know my brother already had it, can I return it, keep OOT and the $25 gift card?

Has anyone tried anything similar?

You believe you are the first to think of this? Returning the game (w/ a receipt) negates the giftcard. I forget what the exact policy is, but you will either have to return the unused giftcard at the same time or they won't take the return at all.

Nah lol I knew someone else tried, but I also had the gut feeling its too good to be true.

I guess I'll sell the second game online, BlazBlue is on sale for $25, goes for $25+ online. I guess it works.
