I use whatever card has the bonus spend. I am currently working on the AAA BOA rewards-- thru AAA of NY. Spend 500/90days, get 100.00 GC for grocery store of your choice. Saw this offer in the AAA magazine, nice little bonus to add to my collection. In about 2 weeks, I have the USBank Travel rewards sig visa (already in wallet)to start using(500.00/90 days) for a 200.00 credit on acct. I will have the CSP in a few days and that will be next for a while,3k/90days for 40k points. That's what i do for spending.
