I ended up going along. Quick summary - lots of Lego, Star Wars, and Funko Pops. Not really a huge selection of Transformers, although there were a few (mostly SS and some Earthrise, including a Sky Lynx) and a loose Mirror. Almost everything was in original packaging; there's not much if you're looking to scavenge some cheap second-hand items. The $10 entry fee only applied between 9:15 and 9:30, presumably to cope with any rush.
