What amazes me about all these stories is the ridiculously low prices the thrift store charged. Here in the Seattle area, everything seems to grossly overpriced in thrift stores.
Goodwill in particular moves items between markets and prices them based on the local economy. Gone are the days of 2010 when you could walk into the Bellevue Goodwill and find lightly used designer clothing that some retired Microsoft engineer was tired of. Now everything's priced higher than eBay and there's no reason to stop by. Everyone else wants to be a "Boutique" and charge high end prices for used goods. Blam…
My best find though is back around 2015, I walked into a Goodwill in Buckhead Atlanta (Atlanta's Beverly Hills) looking for a suit for an interview. Found a matching 5 piece Hugo Boss suit, all in all cost me about $50 but had a retail of I think around $2500. Absolutely insane find, ended up selling it on eBay for a few hundred and getting a brand new suit.
