Yes, if I'm selling something I put a note in my auction that states that feedback will be left for them after they leave mine. Doesn't matter if it's +or -. I will leave them + as long as they complied with the auction rules and meet their part.
Now when I buy I will leave the feedback as soon as my item arrives and I look it over.
Due to the recent rash of feedback extortion I have had to go this route.
I miss the old days of eBay.
When I was active on Ebay, I would only leave feedback - appropriate feedback, not retalitory - after feedback was left for me. It was the only way, sometimes, that I knew if the transaction was completed satisfactorialy.
After having several feedback hostage situations, I no longer leave feedback first as the buyer. I think the seller should leave feedback right away if the buyer pays in time. I'd just as soon not get any feedback at all than risk somebody trying to give me a negative.
As the buyer, I won't leave feedback until I receive the item and it is as described.
Andrew, your method is the same as mine. The thing is, the buyer generally has the seller by the balls (excuse the expression ) until the buyer receives the item and leaves feedback. As the buyer, it's simpler.
