I have sold some ice skates that require age verification. I have charged the buyer £8.95. When I sold some ice skates 4 weeks ago UPS charged me £14 to have them collected. It’s now charging me £24. when I listed them the Royal Mail option was available but now only UPS is available. I am using the eBay app and can’t access eBay from a desktop. I can’t go to the post office as I am a charity shop and the postage is charged to a card that I don’t access to. Will the post office put a label on for me? any other ideas please?
