"Also I've noticed an increasing trend, at least at my local Goodwill store, if items being priced laughably high for a thrift store."
Oh, it's not just your Goodwill store.
My Mother was in the book and antique business for many years, and often scored some decent stuff from Goodwill.
Then, maybe 10 to 15 years ago Goodwill decided that it was also in the antique business, and prices started to jump, especially on their online stuff.
Problem is, they were charging antique prices for stuff that's absolute crap.
Last time I was in a Goodwill store was maybe 4 years ago. I needed a couple of cheap blankets for something, I forget what...
Stained, frayed, torn blankets/coverlets that would have cost maybe $50 new were priced at $80 and up.
I saw a couple of Reader's Digest condensed books.... $15 EACH.
I've never bothered going back.
