I've just found this on Martin Lewis' Moneysavingexpert.com (it's actually in a guide to selling on feebay!)
Other Auction Sites
While eBay is massively dominant, cqou* and eBid are sizeable auctions. Their advantage is they charge sellers less than eBay, which means some prefer it. On the downside, your auctions are likely to get less exposure than they would on eBay, so could get fewer bids.
Comparing charges is tricky, because all auction sites have different fee structures. With eBid and cqout, there’s no initial listing fee; they only charge you once your item sells. Therefore, it’s well worth putting a few items up, with a high start price – you never know!
If the item does sell, eBid charges a flat 3% of the items final sale price. Cqout is more expensive: it charges up to 4.5% on items up to £50 (then 4% on the remaining £50 to £200, then 3% on the remaining £200 to £1000)
All of these compare favourably with eBay’s closing fees of up to 7.5%, plus listing fees.
