Sure, you have to sign up for their credit card, but you don’t have to use it! Well OK, you have to use it once to get the $100 off.
Upon approval, the card will be automatically added to your Amazon account. Just use your new card to buy the Kindle and they’ll instantly knock $70 off the price right there on Amazon. Then Chase will credit your first statement for another thirty bucks. And you can cut up the card when it arrives in the mail.
C’mon, you know you want one … I do.
