As a rule of thumb, there are items that you should never post immediately.
Anything controversial, especially DVD's, Software, and items that ebay is ambiguous about in it's " Banned from sale" list, should be kept for a few days.
It is great for feedback to have, " super fast shipping ", but if you lose money, it's no good.
You now have to rely on the honesty of the buyer, and that can be doubtful in todays market, especially since ebay changed policy to forget about sellers.
Always put it in your TOS you will post within 3 days unless otherwise requested. If they request otherwise, insist on bank transfer, and cut out PP altogether.
