No disrespect intended
@Nik H , but you ARE paying fees, you just don't know it. There is a transaction fee that the retailer pays. If the retailer wants to maintain their profit margin, they have to cover that fee somewhere. I'm sure they went to all the employees and asked if they would take a pay cut to cover the fee, however I'm just as sure the employees, after careful and concerted deliberation, decided to decline the contribution. How then does the fee get covered? Hmmm, if I can't reduce expenses, I'll have to raise revenues. Who represents REVENUE in the transaction? That's right, you (and me) represent revenue.
Think about that. For nothing more than processing paperwork to move money from your account, to the merchant, they skim 2.5 to 5 percent.
That's why there is a coin shortage. There is no money in hard currency.
