I was just upgraded to the CareCredit MasterCard. The account was opened in Nov 2019 to pay for my dog's chemo (she died in Aug 2020 anyway). I've used the card heavily for vet expenses for the other two dogs and two cats, so it's never had a $0 balance. SL was $6500, currently $12K after CLI requests. I logged in today to make a payment and got a prompt to add it to my login (?). So now I see two accounts. I guess they'll transfer over the existing balance? I haven't received any notification about being upgraded or what kind of rewards the card offers. Sorry for rambling, but I'm so confused.
Congratulations! I got an unsolicited upgraded card in the mail last fall, and had until this month to upgrade to the MasterCard or stick with the retail card. I chose to upgrade a few months ago, and all of my old information was merged with my new card, including the open date. The only thing that changed was the number on the credit card. When I upgraded there was a promotion of 5x points on certain purchase categories like grocery and drugstores. I would assume you'll get some sort of written notice now that you've upgraded.
Thanks, @delaney1 ! This was totally unexpected 😃. Do you know if I'd still be able to use/get 0% promos at the vet? (Pets are expensive).
ETA: Never mind, I found a post from @Medic981 with the info.
