I am assuming you went to the section "Search for Open Shops" and saw a bunch of shops, just not the one you were looking for?
It is unusual even in my 'grab it and run' competitive market for the electronics stores to be taken quickly. You may want to check your profile and make sure you have listed 25 or more miles as the distance you are willing to travel.
Other companies have less problems offloading shops than Bestmark, so if it was a different company I would suggest that the shops may have been gone by the time the scheduler got to sending an email. Bestmark not so much. In fact there is a $100 dinner shop on the board here right now with no takers. If I knew what the restaurant was I might consider it.
