The seller has a rating of 0, so I wouldn't count on it setting a market value because a lot of folks won't buy from anyone without a feedback record. There are too many scams, and so long as "that site" gets their cut from the seller, they will do very little to help a buyer who's been ripped off.

Not to hijack your thread, but I see related problems with BladeForums disabling searches unless you're a paying member. I don't buy from people unless I can see that they have positive comments in the GBU sub-forum (which I can't search anymore), and it's much harder to find knives that I'm interested in anyway. So, I for one am far less likely to buy from the BF Exchange -- I spent a few thousand there last year, and if people like myself aren't buying, then the value Gold Memberships people buy so they can sell are diminished. I could just buy a basic membership, but I won't because, regardless of what they say, I believe they're just trying to force people to pay for minimal functionality that should be free.
