Bricklink, Ebay, and any other trading/purchasing website aside, we actually take trades here seriously. Usually, the person with the lower feedback score, according to the straightshooters thread, would send their items first. Once the item is received, then the member who just received said item will send the original sender their items. We keep this list to show that these people are trustworthy. Sure, it currently needs an update, but we do take our list very seriously.
Since I don't have a Bricklink store, I guess that knocks me out. I would have loved to get rid of all of my piss colored white bricks. Anyway, good luck with your trades.
