So now to push this even further, how do y'all send the fee? Do you just add it to whatever the price for the part is? Here's why I ask. Say I buy a part for 100 bucks with shipping. So the fee is 3.20. I pay 100 and the seller has to pay 3.20. But if I send the fee included in the price, 103.20, then does paypal take the fee out of 100 or out of 103.20? What I have been doing is sending the fee as F&F and the total for whatever part I buy as Goods. I know the difference is probably negligible so it may not matter but I'm not here to make any enemies if I can help it. Some people will get mad over a dime.
