For a year or two Goodwill had an actual computer store full of random stuff. I bought a massive 22 inch CRT there for $50. SCSI drives, cables galore - there were lots of things that you wouldn't find on any other store shelf. eBay was a thing then too, but that store, along with the other thrift stores, was good for a thrifty find. Sometimes there was a profit to be made. Other times it was interesting junk. It was a bit of a low-grade thrill and cheap entertainment for the browser.
