So far for me what has worked is to ask the seller for their ebay seller ID. I give them mine, and then we both only use the paypal accounts and confirmed addresses linked to that ebay seller ID. I also offer names of folks on TE that I have sold to. I also don't sell big ticket items here. You do get what you pay for. We sell to each other off ebay, knowing there is a risk. Another way to go is to list the item on ebay, and post the link here. That works too, but then we need to pay the ebay seller fees.
