You mean requested money from a buyer via PayPal?
Or you requested a transfer of your funds from PayPal?
If it's the first, you're a seller.
So, yes, there's a fee for using PayPal.
Just like a merchant pays Visa or Amex a fee.
It's been there for ages.
Doing the transaction legally also provides protection to both the seller and the buyer.
If it's the second scenario, you aren't charged a fee to transfer your own money.
And I can't think of any circumstance where PayPal charges BOTH the seller and buyer fees for the SAME transaction.
Do you have more detailed info from where you "heard" this?
