**Question From Kate:**

I have the textbooks and solutions manuals for Algebra I, Geometry, Algebra II and Trigonometry, and Calculus. I no longer need them and am exploring options to sell them. Do you buy textbooks?

Thank you all so much for your ministry. It was a huge blessing to me and my brother as we tackled these subjects pretty much by ourselves.

**Answer from Dr. Callahan:**

We do buy them, but at deep discounts. You might be better off on Ebay or Amazon.

We buy used at these prices:

Algebra: $20(we do not buy solutions)

Geometry: $25 (We do not buy solutions)

Algebra II with Trig: $20 Solutions $5

Calculus: $10 Solutions $1
