If you are unsatisfied for any reason within 30 days of purchase, I will refund your purchase price. For the refund, contact me via e-mail or phone (916) 652-4659, and I'll tell you the address to which you can ship your returned printed book (if that is what you are returning). Printed books must be in new and salable condition. Shipping for returns is at your expense unless there is a manufacturing defect.
I don't expect you to agree with everything I say, but I am sure you will find it helpful in your study and teaching of God's Word.
