I agree that Goodwill pricing has gone through the roof lately. They used to be one of my favorite thrift shops but now it seems that they pull all the "good" stuff to sell on their auction site and mark the leftover stuff at like-new prices. I work near one that I used to always go into on my lunch breaks but I stopped going. If there is no treasure to be found, I'm not interested!
My favorite local thrift shops are charity shops for a local health & hospice company. Good stuff, good cause, and good prices. This is the same group that came to my home to help care for me after I had my hip replaced, and I'm grateful. (It was paid for by my insurance, but I am still grateful that they exist and for the good care they gave me.) I have found all KINDS of neat stuff there, and they often sell their sewing machines for around $20-40. (And they test them first & put little notes on the machine, and keep scrap fabric in each machine so you can plug it in and test it yourself. SMART. I don't need one at all but am always tempted just because...well, because they're there!)
Although they did once have an old New Home machine that was in absolutely horrible shape that they wanted $200 for, because it was "antique". Yes, and so was all the rust and filth! LOL Oh well, can't expect perfection.
