i hate it when people post up ebay links, you spend ages scouring ebay looking for a bargin, you find it, and then some egit, posts it up and all the people who can't search ebay that well suddenly all pounce on it and the once bargin you found becomes a turkey shoot.
finding an ebay gem should be the same as digging for gold, do the hard work yourself, instead of waiting for someone to hand it to you on a plate.
only time i guess is if someone specifically asks for it, or if you are selling something you're self and want as much publicity and potential buys possible to push up your profit.
