I bought it directly from his site. I think that is the only way to buy it. www.drseward.com/bpbreeding.htm
It cost me about $150 by the time I got it to NB. Worth every penny. It comes with a 2 vedios, field 67 page feild guid wich is basically the vedio in text and a lot more. It also comes with two really nice laminated charts. One for tracking follicular development in the female and one showing seasonal changes in Togo and the relationship it has to follicular development. Its a great set and I highly recomend it. When you place your order Dr. Seward himself e-mails you to confirm the order and it is shipped the next day.
