We’ve discussed the cheap sources for scrap acrylic before but not since San Diego Plastics moved. They’re now off the west side of Interstate 5 in Chula Vista (1121 Bay Blvd, to be exact). After the move they changed their pricing (though acrylic is still only $2/lbs), instituted a minimum ($30), and put in place a credit card fee ($1). At the same time they improved their stocking area, it used to be a giant dumpster you’d have to dive into.
While there I flipped through their scraps inventory. It’s worth stopping by occasionally as you never know what you’ll find-for-cheap. Today they had some nice mirrored acrylic, some beautiful deep red and navy blue acrylic and lots of clear. I might have bought some had it not been for the new minimum and that I already have an inventory.
All in all, San Diego Plastics still a great source for project acrylic.
