another woman refuses to pay the extra postage

What extra postage would that be?

The addon after sale, when you realise you don't know what the actual postage cost is and now want to charge the buyer more than the quoted price? Which is a nono. Do you acquiesce if your local Wollies/Coles/IGA/Aldi try to charge you more than the shelf price?

I would certainly stand united with anybody who could stop eBay allowing people to resurrect dead threads.
