Been away from eBay for a while but have listed a few items again. I USED to be able to add my own RM postage on the listing page based on their sizes & weight now all I see is Simple Postage that shows as an example £5.20 and 2k with a small size. The items I was selling where maps, and the total weight was over 7k and the box was much larger than the eBay showed. In the old days I could enter all the correct information and see the costs but those options seem to have been removed. I have spent around 2 hours searching here to find out and got nowhere. I don't want to over or under charge so any suggestions as to what to do?
