How much does it cost When you take an American girl doll to the American girl doll hospital for a new wig?

You can't get a new wig for a doll at the American Girl hospital, they will only replace the whole head. This is a problem for many collectors as the older dolls have slightly different faces, and a new head will change their appearance.

Head replacement costs $39 plus shipping and handling ($6.95/doll I believe).
