I've done quite a few sales/purchases on BST and never a problem. The card swapping I have done has been with regular 54 posters and also no problems. I would be a little leary about swapping cards with someone I haven't previously "seen" on 54 if the cards are expensive, I'd try to converse and get some information first. When I have "seen" the seller/buyer/swapper on 54 before I always send the money order or paypal or send the cards right out. Never had an unreasonable delay or lost card on the other end. Much better than ebay....
