Re: Alternative Hypothesis
"You must have very low transaction overheads there."
Most transaction fees in the US are percentages, usually with a monthly fee on top of it for equipment rentals, etc. Depends on the size of the business and the amount of traffic you generate (bigger business or more transactions = economies of scale meaning bulk discounts), but rates of about 2-4% per transaction are pretty common (debit transactions tend to be lower than credit ones). You're also supposed to get a break if you take Chips since there's less fraud risk with them.
