Hmm, I really want to take up this offer, but there are some issues:
1) When I select the UK children's charity, the donation doesn't show up in the basket.
2) When I add the full season to my basket, it claims that it will charge we $35, and continues to do so up to and including the "review your order before we take your money" bit. This only happens if I select the "free" DVD option.
