B/S/T is somewhat limited in the number of auctions you can run concurrently. I think 3 is the magic number. Running fifty auctions a week ain't going to happen without an uproar from the minions. For straight sales listing multiple cards and prices in a single thread is okay, but everyone wants their listing near the top of the board, so if such a thread continually gets bumped to the top, you might have a problem with other sellers. Available via PM for clarification.
