Simple delivery clearly wasn't very thought through IMO. I recently sold an item that the buyer collected in person, however the buyer must not have selected collect in person so of course eBay decided to deduct payment for a label I don't need, I refund the buyer the same amount as they collected, and then I have to put in for a label refund and hope that goes through. 

And the best part, every time I check my account I have a "PAID - POST NOW" message. Nowhere can I mark it as collected or anything. They obviously didn't think through all the possible things that could happen when creating this "simple" delivery service.
