There's 2 methods of payment with PayPal. Goods/services or friends/family/gift. The cost is for making a transaction, someone has to pay it.
With goods:services it's the seller, with friends/family/gift it's the sender.
Bottom line is PayPal wants to get paid for handling the $.
Some sellers will ask for the buyer to send as friends/family/gift to keep from paying the transaction fee.
