May stop being accepted by (some?) merchants/retailers. Visa/MC agreed with a group large retailers that that wouldn't be necessary going forward. Retailers have been POed for a long time that if they accepted one card of a brand, say Visa, that Visa said you had to accept all with their brand. The higher the rewards of a card, the more the retailers had to pay Visa. We'll see what happens. The three cards we mainly use have no annual fees, but pay back 2% or more. Recently have had some large payments that the retailer wanted +3% if we used a card. We declined to use one.
