PayPal rules

You cannot use ebay and want the BUYER to pay the Pay Pal fee.
Yes, that's in their agreement, rules.
A private party sale, on the internet, between both the buyer and seller, Pay Pal has no control over wording in an ad if you want to be paid Family and Friends, and your buyer pays you thru that format.
You know how much business Pay Pal would loose, if they said no Family or Friends payments.

Pay Pal is making 30 cents on the transaction wither it's Family or Friends, or Goods & Services, so you do the math on how many transactions Pay Pal does each day, for the revenue they bring in.
And it's even more on a foreign transaction, say Canada, Europe, Asia.
I'll tell you this much...i still hold a Dutch bank account, as well as my American one
When I need to send money to family back in the netherlands, I transfer it from my one PayPal account (linked to the US bank account) to my other PayPal account (linked to my Dutch bank account) and the transfer is cheaper and quicker then if I had walked into a branch office of my bank to make the transfer
