Thanks for your support and glad you could connect here. I usually don't deal with books unless they're textbooks or rarer ones like these. On top of that, I have so many free books on the curbs available, that I usually skip the book sections at thrift stores or just take a quick glance.

Glad you have made books a successful niche for yourself. I could probably learn a thing or two from you! Given all of the general stuff I sell, I don't have the discipline to handle books in high volume like that, but there's definitely good low-risk money there. The signed or 1st Ed. copies are the best finds. Always a nice feeling when you get one.
