All our books are sold with a money-back guarantee. If you don't like a book, send it back, in good condition, and within a reasonable length of time, and we will refund the full cover price (but not the postage).

We usually ship within a day or two, however sometimes there may be delays of up to a week depending on if we run out of books or take off to do some diving. If you haven't gotten your order within two weeks (or for overseas orders. three) let us know!

Please note that, when multiple books are ordered, we usually ship them in several packages to take advantage of Priority or Global Priority rates. In addition to being faster, the flat rate envelopes also seem less likely to get hit up for import duties or tariffs.

Please don't ask us for Overnight or Courier Service unless it is really essential. Many customers casually ask us to send books that way, then squawk when they get the bill - sending a single book to Canada by overnight courier can cost $50, and to other overseas destinations, as much as $100. Also, they may require an extra charge at your end for a customs broker since our books are merchandise.

So if you request any form of special handling, we'll Email you to confirm that you really want it, which will waste a day, then it may take another day for the pickup, with the result that the book will end up taking just as long to get to you as if we'd sent it right away by Priority Air.
