Quoted from shacklersrevenge:
Lots of deals done before and lots done during. You're going to a pinball buffet, you'll have plenty to feast on. Rows of games for sale and projects too. Have fun!
This may be true but unfortunately I've heard from many that the people who camp before the doors open always get first dibs and buy up all of the best stuff which leaves mostly undesirables before lunch time. That saddens me and is making me rethink taking the trip out. If it were closer to me I'd make the trip regardless of what was left but I'd hate to travel almost 3 hours to come home empty handed
