the ebayer usually goes with auctions and his average price is 25.00. his fee's are:
0.65 to list (as a basic auction with a picture in the gallery)
1.31 final fee (5.25% of 25.00 dollars)
fee's are 1.96 for ebay. for paypal using the same 25.00 + 9.99 shipping, the fee would be 1.56. PayPal charges 2.9% + 0.55 per transaction.
his total fee's would be $3.51 (again using just the average of 25.00).
this might be a bit more or less depending on a few different factors but it gives us a great idea of the fee's.
