I made an offer on an item on ebay for £40 plus p+p, the seller declined my offer but said he would accept £50 including postage if I paid by Paypal outside ebay.
Should alarm bells be ringing - is he just trying to avoid ebay fees and save on postage (which is priced at £5) and therefore meeting me half way? He has 100% positive feedback over the last 12 months.
Just not sure how much legal protection I would have if he decided not to send the item at all.
