That's exactly what I was concerned about. With a fixed rate of 7¢ on a transaction, or even as high as 40¢ or 50¢, you have a fixed cost. It's there. The cost of the transaction, whether it's a large or a small one, is going to be the same. Whether it's on $10,000 or 10¢, that transaction cost is basically not much different. To go to, say, a percentage-based debit fee to make that transaction happen could be devastating to the small grocers.
