Field notes
The controls pair four pricing approaches—card cost only, surcharge, interchange-plus, and flat rate—with $25, $100, and $400 sale amounts. The visible example breaks out five card categories, while the page says its figures are industry averages and exclude processor fees; actual costs depend on the merchant’s agreement, business, and transaction mix.
