If you're looking for an autographed copy of Punk Farm on Tour, I signed a ton of stock for the following bookstores:
Barnes & Noble - Worcester, MA; Fairless Hills, PA; Carmel, IN; Wilmington, MD; Canton, CT
Wellesley Booksmith - Wellesley, MA
Tree Top Kids - all VA, MD, DC locations
Aladin's Lamp Children's Books - Arlington, PA
Politics & Prose - Washington, DC
Borders Books and Music - Wynnewood, PA
They may even have some signed stock of other titles. If you're looking to cross some presents off your list, try giving one of those stores a call.
