I've wondered that too. We put everything we buy (even my daughter's
college tuition) on our Discover (and pay it off next month, of course)
and get the cashback discount. Keep a Visa and American Express for the
few places that don't take Discover (like Costco).

I always figured that Discover charges the merchant more than Visa...
but your posting suggests otherwise.

actually PAYS you to use their card -- yet they are a distant third or
