It's been a long time since I got an unsolicited CC.

This puppy arrived in today's mail. I renewed my Citi AAdvantage MC for the usual bonus equal to the annual fee and double miles for a $750 spend. (I have yet to see the credit.) But two new cards arrived. MC and AMEX.

I see no reason to anything but reject the AMEX. My Costco AMEX has a much better reward structure. And frankly I know of no merchant other than Costco that takes Amex but not MC.

I use the MC to keep my AADvantage points from expiring. Travel budgets are much reduced of late.

So, is there something I am missing? Is there any reason to keep the unsolicited Citi AMEX?
