I'm originally from Milwuakee, Wisonsin, and wanted to let everyone know of great off beat shop there, that has an online store:

American Science and Surplus

https://www.sciplus.com/

When I was looking to build a teleportation device, I picked up wide variety of switches, buzzers, lights, etc. They also have great selection of bottles, bags, and a surprising array of other items. Their stock is constantly rotating. Just wanted to post as a resource to others. Enjoy!
