Listing clearly showed item location including Australian postcode. Buyer paid for local pick up. They had the option to pay for postage but did not. Now asks for refund due to pick up being 'too far' . Do I have to give refund?
I'd like to purchase a large item from someone I bought from about 6 years ago. Can't remember seller's name and the purchases list only shows 2 years back. How do I find older transactions?
