I got the amazon prime card about a year ago. I only use it on Amazon or purchases outside the US. No foreign transaction fees which work out well since I bought stuff from Amazon in UK, Germany and Italy. Shipping is surprisingly cheap but slow. Just bought 29 3d blurays yesterday from Amazon Germany.
No regrets about having the card. Only drawback is that its another thing preventing you from ever dropping Amazon prime but I don’t plan on doing so.
