It's no secret that everything in film is expensive. Milk crates...super useful for storing gear and bringing on jobs are kind of pricey.
So I just get them from dairy outlets.
Here's one on ebay:

Also Teradek screws go for $20 - for a 1.5' 1/4-20 screw you can get it from a pool supply store for $10 - 2008 Thumbscrew 1/4 - 20 x 1.75 inch - from Masterspa.com
Fun to get deals like that.
