PS It's not 4% anyway. It's 2.9% plus 35 cents or some such. Where do people get the 4% number from anyway?????
My mistake, I used the 4% off the top of my head without checking. It is actually 2.9% plus 30 cents per transaction. So the people involved in such a transaction are selling their integrity cheaper than 4%.
In addition, someone above wrote:
Both ways, if you send the money as a gift the sender pays the PP fee if you just send the money as a regular payment the receiver pays the fee.
Not exactly correct, if the sender uses his paypal cash balance or pays from his bank account there are no fees. Otherwise the 2.9% plus 30 cents per transaction applies if he funds it with a credit card, debit card, or paypal credit.
