I have been to a few, and yes, the problem is getting rid of ten medium boxes of old tshirts when all you wanted was the bicycle. You have to have an outlet like a flea market table or secondhand store.
We have a Christian mission thrift store here that we donate to. They sell stuff to make money and also box things up to send overseas to poor countries. Apparently some of these countries use old tee shirts and clothes to make bandages out of. Pretty sad if you ask me but that’s probably what we’ll be doing here soon. I’m sure they wear some of them too.
