You just don't get it do you?
There are reasons someone might wan't to ask a 4% fee, on doing a payment transaction.
Nobody is going to make any kind of money "screwing" anybody out an additional 1%.
Your really going to get rich doing that?
Give me a break.
Really, you need something better to do with your life, if 1% is giving you such a big heartburn.
Then what do you do when somebody sends you the bill for XXXXX amount of dollars for parts, shipping, Pay Pal.
You don't know if the seller is getting 3%, 4%, or any higher amount.
