American Express will place a cap on the amount of bonus cash back earned on supermarket purchases made with the Blue Cash Preferred and Blue Cash Everyday cards. Currently, both cards earn 6 percent and 3 percent cash back, respectively, on supermarket purchases, with no limit.
“We set the cap at $6,000 because it more than covers what the majority of cardmembers are spending on supermarket purchases,” said Leah Gerstner, an American Express spokesperson. “Therefore this change will have no impact on most cardmembers.”
For Blue Cash Everyday and Blue Cash Preferred cardmembers, the change becomes effective when their accounts renew on or after Jan. 15, 2013.
Current cardmembers can see the notice of the changes to their accounts in their October statement.
