does the successful bdder pay a fee or perentage

Yes there are fees on top of the winning bid. I bid and won a car for $900 and had $400 in fees. Still was a good buy.

Both! It's best to visit their website. There are three extra fees and the more you spend the higher these fees are; until your bid is high enough it goes to a percentage.

Fees :)

The buyer and the seller pays fees
