This is a good idea. I've not seen the value in the past, but this thread is perhaps convincing me otherwise. In other news, I just had a similar experience on Ebay - seller had two similar items listed separately, and sent me the wrong one. I'll say - Ebay is not a seller's marketplace, but sure is a buyer's marketplace - returned item at no cost to me and all sorted within 3 days. So that's what those hefty fees must be for....i have and Buyee helped fix it. It did cost me a lot to send it back to Japan. Pretty much ruined a fair deal making it a really expensive deal.
I bid on and won a titanium 7C43. Seller sent a titanium 7N42. It was much larger and really ugly. I don't know if it was an honest mistake. Seller has both watches listed on Buyee. The auction for the 7N stayed up for a long time after seller knew it wasn't in his possession.
You can have Buyee send you pictures of the item before they ship. The fee is reasonable and far cheaper than shipping back. I use it when I purchase anything high value or I really need the exact thing I bid on.
