You need a padded envelope or box big enough to hold a return padded envelope and the book, plus a return padded envelope.
Address the bigger box/envelope to MJH.
Address the smaller envelope to yourself and affix enough postage (
http://www.usps.com has a price calculator) for it to be mailed back to you. Estimate this by weighing the book inside the return padded envelope. Or you could include $5 or $10 etc.
Put the book, cash (if using) and envelope addressed to yourself inside the box/bigger envelope.
Attach enough postage or visit your Post Office to get it weighed and shipped.
It really is simple
