I sell sporadically on ebay, and listed some clothes last week.
I see that Ebay now give limits for postage prices...fair enough.
2 of the items I sold were in the coats/jackets section, maximum postage £4.75.
One was a gilet, the other a cotton jacket...not big heavy wool coats.
When I went to post them, the cheapest price was £5.35.
Are Ebay out of touch here?
