If they base the debit transaction on a percentage, looking at what I did last year in debit, which was 17% of my sales, it would actually cost me $4,500, according to the rate that Visa offers me right now. I'm assuming that it wouldn't be anything less than that, and I'm assuming that debit costs would go up if they were on a Visa debit card. It's a real cost, and it means about 20 hours a week of employment and another extra cost that we can't afford.
