I just want to let you all know we have about 10 people interested in buying the book. I've been informed by someone who ships books that the USPS raised it prices a few weeks ago and the book might not fit in the $4.95 priority box. If that's the case the next box is $10.35 for shipping . I'm sorry about this, but there is nothing I can do about it. NADA is not making any money off this group buy. We're doing it to help promote discus and their care.
