Back in the day,you could go antiquing at a Goodwill and find some good stuff.
The Goodwill Store just off the campus of Iowa State University gets all the used computers from the university. I used to buy ‘boxes” for $99 and install all my favorite hardware “goodies” to bring them up to date.
Their regular clothing is also insanely overpriced.
Thankfully our Salvation Army, and Bible Mission Thrift stores, has good merch at bargain prices.
