Oh yeah--The Costco Amex gives you 3% at all restaraunt--so I carry both the Citi AA Business cards to use at restaraunts where I know I can get the 15% back (they are in the Idine program) and use the Costco Amex at all the others.
Sometimes I go to an Idine restaraunt without realizing it so I have my Costco card registered with a seperate Idine account that gives me 10 miles per $.
(fyi--Idine is now called Rewards Network -- rewardsnetwork.com)
