EBay and PayPal are nice to use, especially for high end stuff, but their combined fees come to a lot. If you have a business PayPal account and use eBay, here are two examples of what the seller pays:
(1) on a $6.00 opening bid item that has one bid and sells for $6.00, the seller pays $1.14 or 19% of the $6.00 in fees. Ouch!
(2) on a $50.00 opening bid item that has one bid and goes for $50.00, the seller pays $6.15 or 12.3% of the $50.00.

And the above examples don't factor in the times you get no bids.
