Ive just started putting a mental business plan together on this. A few obstacles I see: 1) in the high end, is a UPS store or equivalent going to have a staff member on hand with enough expertise to vouch for a product? 2) condition is sometimes a bit subjective. One persons "Mint" is another persons "Very Good". When you have quality disputes, what are going to do? cancel the transaction? that is an expensive and painful process for all involved. I think if you shoot for the least common denominator and can do the following there is some value to be added: a) is it not a brick (unless he is selling an actual brick :) ) b) is it the brand and model that the listing advertises c) if it is easy to do can you verify it is in working order when the item is packed and sent away. I still see some wiggle room for problems, but I do think that being able to prove you shipped the item is important. Furthermore, if the seller sold an expensive item, didnt he insure it? If the item "didnt arrive" then we have a different problem. The seller keeps his money, and the buyer works with the insurer(who has a vested interest in not paying so will likely investigate a bit) to get made whole again.
