Landfill them.
My family has been going through this, like most people who have accumulated a lifetime of stuff that our kids will never want or use. Like how many generations' sets of fine china do people need, that isn't microwave or dishwasher safe? We don't even use it ourselves. Books that nobody will read?
Folks talk about "saving it from the landfill," but if you keep it, then your house becomes the landfill. It's the same amount of stuff. Selling it to someone else means that their house becomes the landfill, and it gets hauled around the country.
The thrift store is a way of making you feel like you're "saving it from the landfill" while getting it out of your hair. It's a psychological service. There are huge landfills of used clothing in Africa and South America.
I throw stuff in the trash with no regret. The last frontier was books. They're sacrosanct, right? I finally realized that my college textbooks are obsolete, the library won't take them, people have figured out better ways of presenting the information -- for free online -- and I never cracked the books even in college.
I threw physics textbooks in the trash. It felt liberating. There, I said it. I only have one left, my first edition of Horowitz and Hill,
The Art of Electronics, which I did read cover to cover, twice. I'm human.
Both of our kids are now old enough that we can make educated guesses about their interests and life trajectories. This means we can stop saving things for them "in case they might take an interest." This includes all bass related stuff, so I'm ready to put some of it on the Craig.
I'm convinced the only ways to save it from the landfill is to truly recycle or re-use it, which only works for a small fraction of the stuff, or not let it into your house in the first place.
