I have the Amazon store card which I loveee! At one point, I did have the Chase Amazon Visa too...lol. The account is closed now. I found better cards to suit my use while on Amazon--didn't really like the shop points rewards on that card. I like the financing options Amazon store card offers on eligible purchases. It's good if you are planning to carry a interest free balance! I got 6 months no interest on 200 dollars! LOL.
I have the Chase Amazon Visa. For some reason this card offers a 1% fee on all BT.YMMV That is a pretty good benefit if you need it.
Like the title states?
I have both. I use the heck out of my store card because of the 0% financing deals. I don't use the Chase Visa that often. It sits at a zero balance (high interest rate) and I use it every now and then to keep it active. I am trying to get it converted to the Chase Freedom Mastercard.
