Best credit card for Amazon

I’m a very happy Amazon Prime customer. The free shipping and other benefits make the $119 annual fee well worth it. I also have the Amazon Prime Rewards Visa Signature Card, which I use to make all my purchases on Amazon, because you get 5% on every purchase you make on the site. Amazon is offering a $70 Amazon.com Gift Card instantly upon credit card approval when you apply for a card. — MF
