I prefer physical as well but my problem is I'm hitting a shelf limit. My plan is to donate the books I don't care about to friends or the library to open up space.
Consider donating them to the Internet Archive OpenLibrary if they don't have them in their catalog. It's very inexpensive to mail if you use USPS' media mail class of mail. I just sent a 13x13x16 box weighing ~10lbs to them for ~$8.
This is exactly what I do with old books. I keep the ones I really like and give the rest to any place that accepts book donations. Might as well, I am clumsy and have busted two kindles, so I'm all aboard the physical book train now.
