Beat me to it bro. I use ebay heaps. But thats for buying... havent sold anything on there in ages and I CBB with international shipping as not many kiwis use it... but I just checked:
First 5 items per month have no listing fees - only pay when they sell. Insertion fees range upto $4.00 + $ for extra features.
Success fees: (US$)
$0.01 - $25 - 8.75%
$25 - $1000 - 8.75% of the initial $25.00, plus 3.50% of the remaining closing value balance ($25.01 to $1,000.00)
Over $1000 - 8.75% of the initial $25.00, plus 3.50% of the initial $25.01 - $1,000.00 plus 1.50% of the remaining closing value balance ($1,000.01 - closing value)
