Oh, there are still good finds to be found, no doubt. Some people have fun searching for designer pieces - and they can still do that. My objection is more to crude pricing - which ends up alienating plenty of people it doesn't need to.
The thrift store has never been about getting cheap junk, it's about getting second hand clothing. They're not competing with the likes of Shein because they can't. Ultimately, those consumers who do want cheap junk should be alienated, because that don't offer what they're searching for.
