Quoted from TigerLaw:
That is helpful for this purchase but you have to find a distributor that doesn't want to charge you extra for using your card and still give you the street price or whatever shipping deal he would normally cut.
What I'm finding is if a distro will accept your credit card so you get the rewards they either want to charge you 2-3% or they want to raise the price or not give you free shipping if you worked that out prior to discussing payment method.
With a game as pricy as DI, getting your full credit card rewards without a penalty is a niceness perk to reduce cost.
Is the credit card fee true for direct sales as well?
