I can't believe I'm saying this because normally this would probably be the type of thing I'd consider doing, but doesn't anyone else think buying a Kindle/getting the code/returning the opened Kindle/using the code to be rather unethical? I mean, believe me, I've exercised the liberal return policies of Best Buy/Target/etc in the past, but I try not to abuse and would NEVER return something after having "stolen" (although that word is rather strong) something. Yes, I've purchased laptops and yes I've returned them opened if they did not meet my needs, but to me this is really pushing it since you're essentially taking something for nothing from Amazon, and also forcing a store to take a hit on the opened item that you're returning for no reason.
I bought a Kindle with the intention of getting the code and using it, but I never once considered returning it opened. I have no use for a Kindle so I was either going to give it to my wife or sell it. As it turns out, I decided against the whole thing so I WILL be returning it, albeit still sealed in the box.
