Why not get a gift certificate for your herding friends?

The certificate (a.k.a. Robin Bucks) is redeemable for lessons, herding tests, or gear such as On the Lamb t-shirts, sweatshirts, flag poles, whistles and other neat stuff you can pick up next time you come to the ranch.

You pick the amount, the receiver picks what they get to use it for - in return you become a pretty awesome friend...
