Android Market lacks gift cards?

Anyone know if there is a way to give Android Market credit? Need to give gifts to a few kids this season who have Android phones but too young for credit cards.

If there really is no way to do this, I think that's a huge hole. Especially now that music is such a big part of the market. Especially with the number of young people with Android phones (which tend to be cheaper than other options). Especially this time of year.
