I'm selling all the materials for the home study course - cds, booklet, birth partner guide, etc. I just purchased this past fall so it is the most up to date version. It retails for about $160 and I will sell it for $100 including shipping.
PM me if you're interested! I've sold diapers on the CD board and also on diaperswappers (same username) so you can look at my feedback there as a seller.
