Right, another person who has never met me calling me a liar. The processor I use now, who is a member here has the option of doing exactly as I have stated. If I put in a charge of $500 it adds 3% and your card is charged $515. When it processes, $500 is deposited to my account. My invoice shows $500 total and that is what I receive. The credit card receipt that prints out of my terminal and is given to the cusomer shows the added fees and a total of $515. There is nothing being "sold" here. I am simply stating facts. Not all card processors work the same way.I'm fairly confident that most normal men, and even women understand....however what is being "sold" here is that the card companies pack the charge....anyone with a brain cell understands that the credit cad companies charge a "fee" my wife had a retail store for many years....she processed card payments daily...what is being "sold" here is that the card company back charges the fee to the consumer, when actually the seller simply states a cash discount, then adds the fee to the charge...so, the processing company/bank is not doing anything else that processing the charge, which the merchant has added the 2.5% fee, or what ever it may be to the charge....It's not rocket science....so, you buy the gun for $500....the seller has already stated that the price is a "cash" price, you agree to allow the merchant to add the fee to the charge, which increases the actual charge to $500 plus the fee...so the charge comes in at the increased amount nothing done by the processer, all done by the merchant....
