Amazon Prime credit cards is a good choice for customers with an eligible Prime membership – it offers 5% cash back on Amazon purchases. Don’t forget that Prime membership costs $99. If you are not an eligible Prime member you may choose from other credit card with cash back rewards. For example, the Discover it® Cash Back credit card offers 5% cash back at different places each quarter like gas stations, grocery stores, restaurants, Amazon.com and more up to the quarterly maximum each time you activate. Amazon.com appears in 5% cashback bonus calendar in the 4th quarter this year, which is from October to December 2018 on up to $1,500 in purchases. You will need to activate 5% cashback bonus to be able to earn it. When you reach the cap, you will continue earning 1% cash back on all purchases. Also Discover will match ALL the cash back earned for the first year (provided you are a new cardmember). You can redeem rewards any amount, anytime, it is also possible to use rewards to pay at checkout at Amazon.com. If we consider the interest rates of these two cards, the Discover it® Cash Back credit card comes with 0% (14 months) APR on purchases, the ongoing APR is 13.99% – 24.99% Variable. That’s also a great feature.
