My recommendation would be to go on Friday night if you can afford it. Saturday morning at 10:00 AM the tech day starts and it can get packed really early. The sooner you get there the better. Also that's the best day to pick up bargains as they have the largest supply. By Sunday afternoon, all the best stuff has been claimed! I also recommend staying until the last of the raffle drawings on Sunday afternoon,
if possible. They raffle off really great stuff.
