Backlash Tampa merch

Do they eventually sale the date exclusive merchandise after the event??? I attended Backlash last night and after the event, I drove to the Backlash store and parking was nowhere to be found near the store. Alot of restaurants and bars nearby so I understand. I was interested in the magnet and pin but they are not sold online as of yet. I do not know if they sell them later online just to get rid of date exclusive inventory.
