My definition of expensive for thrifting is- if i see something the same if not more expensive than when it was brandnew. My local goodwill was selling a bunch of old faded glory clothes & some of it was up to 10 bucks. Probably what it was new when walmart still carried them. Ive started donating to local businesses because ive worked for a "big" thriftstore & i used to get in trouble for not marking it as high as possible.. because worst case was if it didnt sell, we'd retag cheaper
