I clearly state that I do most of my posting on Fridays or Saturdays, becasue these days I have a spare 30-45 minutes to stand around in the post office waiting to get served.
Anyway, dress sold on 29th May ( a friday) and was paid on the saturday. So I posted it the following Saturday,which I what I say on teh ebay listing. She says she emailed me lots - she did twice, each time I pointed out the reference to posting in the listing! SO now, out of about 9 feedbacks, 1 negative has dropped by score. All the others say the item arrived quickly and didn't have a problem!
