Dialing for answers on credit card processing fees

A while back I grumped about the "$X minimum purchase" claims some merchants make (which are in violation of Visa & Mastercard contracts). My friend Matthew, proprietor of Roots & Grubs, went further and actually did some investigating to find out more about what processing small transactions actually costs merchants. It's a great, very informative post. Though I am dubious about this whole "making calls for information" thing. It sounds very un-bloglike, involving effort and journalism. Aiee!

(And hi! I'm alive again.)
