I have bought & sold a lot of items on Ebay without any problems.
Today I listed 2 items with Ebay's offline listing tool. After I clicked upload a red warning message popped up for an instant. All I caught of it was that "PayPal will hold payment". I called Ebay & the story I got was that on some items PayPal will hold payment for up to 21 days or less if the buyer leaves positive feedback. The item I listed was a new computer drive enclosure.
I let them know that I was not happy with this policy & deleted the listing after getting off of the phone with them.
The biggest issue I have with this policy is I was not given notice before the item uploaded. This notice could be given at the same time they let you know what the fees are going to be.
Ebay has become very Seller unfriendly over the last few months.
