There are many options in addition to the Amazon.com Rewards Visa for shopping at Amazon. Although their rewards are competitive, earning 3% back on Amazon purchases and 1% on other purchases, the sign-up incentive leaves something to be desired. The namesake card only affords $30 off. There are several cards that will give you $100 or more in the form of a digital gift card to be used at Amazon.com. The difference is the Amazon.com card will give you the credit instantly on approval. With the other cards you will have to meet a minimal spending requirement first. There are also other cards that will afford rewards of 1.5% back on all purchases. Check out some other promotional offers that offer up to 5% back in rewards.
