Just like Bearc, I like to use EMT for the fact it costs the dealer nothing. My buddy (owns a mechanics shop) gets charged a monthly useage fee for having his debit machine. On top of that, if someone pays on Credit (depends on type, MC, Visa, AE, etc) he gets charged typically between 2% and 4% to process the payment. So, in order to keep the lights on and food on the table, those costs are passed on to you. If everyone payed in the way cheapest for the dealer, perhaps they could in turn pass the SAVINGS on too
