which is against the ebay rules: Ending Your Listing Early
and always has been! Its an auction. If you want to sell via multiple routes use a Classified / Best Offer approach. The concept of an auction where the seller can withdraw undermines the system.
You can advertise on here by pointing people to your ebay ad. You see we are not precious because we don't charge any fees!
Its not an 'extra' fee, you agree to the fee upfront or, on the otherhand, their users are just taking the mickey and using the advertising prowess of ebay with no serious intent of completing the transaction on ebay. I'd guess this is a particular problem with cars, boats, bikes etc where people need to collect, its high value (so high fees) and often people want to test/inspect. Ebay's pricing model is based on a fee for the ad and then a fee for 'success' if you cut them out the success but still sell that seems unreasonable to me. I note they are allowing people to do it once per annum without penalty anyway so it really is for those trying to circumvent the system.
Well not much point moaning here - ebay aren't regular visitors! However are other people not allowed a different view? The best way to convince any corporation you don't like their pricing is to stop paying them. If you want their services accept their pricing or find an alternative.
maybe you could set up your own auction site, invest in its development, market it and run it - and offer lower prices?
