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)
^ Just to be specific its the "True Earnings" card
i think 3% cash back is worth lot more compared to miles earned.
Double dipping with Idine is great too
