In another thread, it was mentioned that AmEx had a deal where you could get $25 back on a $75 (or more) purchase on Amazon. Someone said it works if you buy an Amazon gift card, so essentially you get $75 of Amazon "credit" for only $50. I don't really buy things from Amazon, so even though I am signed up for the deal, I haven't bought the gift card because I don't know what I would buy.
So I ask you: What is the best "bang for your buck" from Amazon? Surely there must be something to convince me to take advantage of what seems like a pretty good offer.
