You could just use Gyft and get a discount with BTC yourself lol.
You don't even need to use Gyft at all if you are wanting to spend bitcoins to purchase items on Amazon. Services such as purse.io take bitcoins in exchange for whichever Amazon items you would like to buy and you get very significant discoubts of up to around 20%. The one time that I did use them I got a 12% discount on the coin, which is much better than any other exchange rate you can find anywhere else. Of course, this comes at a cost for the buyers of bitcoin, but it does make this service kind of useless, not to say that OP doesn't have much of a reputation.
