Oh Yes, YES, YES .... says the ebay CEO as he rubs his hands with glee .... More PayPal profits for me !!!!!!!

When you do any sort of refund thru' PayPal, part of the refund comes from the PayPal commission you were originally charged.

If it's a full refund, PayPal returns all the commission & keeps the 30c transaction fee.

If you do a seperate transaction to make any sort of refund, PayPal keeps the original commission, charges you an additional 30c transaction fee plus commission on the new transaction.
