The American Express Membership Rewards catalog is available online at Rewards.AmericanExpress.com. American Express customers enrolled in the Membership Rewards program can log in to check their point balance and see what rewards they are eligible for.
In May of 2015, American Express announced it would be launching a new loyalty rewards program called Plenti. Plenti will partner with various retail brands and allow members to earn points even when they are not using their American Express credit card. Existing American Express Membership Rewards points will be transferable to Plenti, and every 1,000 points earned will convert to $10 in savings.
