This swap is unique. I've never been to another like it.
It's a one-day consignment swap. No fee to put bikes or parts in. Pre-registration of your bikes and parts will save a lot of time waiting in line.
You drop your bikes/parts off between 8 and 9:15 am. If your bike or parts sell, you get cash minus a 15% consignment fee. If it doesn't sell, you just get your bike or parts back.
In years past, I got some incredible deals. Chrome Schwinn Voyageurs and SLT's for $50 or less. But you have to get there earlier than 10 am (when it opens) to get in line, as those deals go fast.
It used to be a two-day swap and 10% consignment fee; now it's a one-day swap and 15% fee. But it's worth it.
Last year, it rained all day, and all my bikes were soaked that didn't sell. But I sold a few anyway.
Watch out for the parking lot/sidewalk lizards who try to intercept you before you enter the swap grounds and lowball you.
Also, wouldn't hurt to bring an allen wrench and check for stuck seatposts, stems and the like.
