I love reading the used furniture listings at craigslist. There’s always a ton of interesting pieces.
A blue velour pimp couch?
A sweet atomic age blue-green couch
By far my favorite item is this Microwave & TV cart. It’s lazy owner can’t even take the time to take the toilet paper out of it or move the dog out of the way in the picture.
You can also buy a ton of decent used computers on craigslist.
Just remember, be careful of swindlers! Don’t pay unless you’re in person.
