Thailand guidebook group buy.

I'm planning a trip to Thailand next year and was just looking into buying a guidebook. I want to pick up the 8th edition (2012) of King Climbers, but US sellers are asking $45 + shipping for it. If bought directly from the authors it's 1050 baht (about $33) for the first book, including shipping, then an additional 600 baht (about $19) for each additional book shipped to the same address.

Does anybody else need a copy of the book? Depending on the number ordered and my shipping costs to get them to you we'd probably be looking at somewhere around $25/person.
