... Made an offer on a buy it now or offers item, they've messaged saying yes to the lower price but send my PayPal details directly so they avoid paying eBay. Does anyone know if this is legal/a good idea?!
Dodgy? Lmao, it's not dodgy, it's just desperate sellers trying to avoid eBays ever growing fees. As has been said above as long as the item is paid for with Goods and Services you are completely protected for 180 days.
