This is the simplest return/refund policy you’ll ever see (especially one written by a lawyer):
If you’re not happy, I’m not happy.
If for ANY reason you want a refund because you’re not happy with your book that you purchased through this website, simply email me at within 30 days after purchase, tell me that you want your money back, give me your order number, and I’ll refund your order.  It’s that simple!  I won’t even make you ship back the book – there’s no need to waste shipping costs and effort.  Instead, give the book to someone else who might enjoy it.
