I honestly thought you were meaning to give them trash. I never feel bad about dropping off old furniture and junk at chain thrift stores making profit run by wackadoos. Dropping off after hours saves me a trip to the dump. Much cheap for me too.

My fav place to get books is libgen.is. They usually have what I want in multiple formats. I read on my phone, so I always have a book with me.

Seeker app for Android highly recommended
