It's hard for me to answer because I don't know the system costs. Costs are currently very well put together. The credit card companies, the card issuers and all the businesses that bill us fees... We have final costs. We're billed a rate or an amount that we have to pay on an invoice and we receive very little explanation.
You ask me what their profit margin is. I can't tell you. It's normal for those companies to make profits, but we want to make some too. The example cited earlier is fairly clear. If our payment rate on a credit card is higher than our profit margin on a product, we might as well shut down. I don't understand how you can let that go.
