Save A Houston Librarian, Buy A Book
The Friends need volunteers to help set up, count the books sold, resort books, help customers, smuggle weapons, and other assorted tasks. So get to it. And while you're at it, you should consider joining the Friends. Membership has its benefits, including entree to the members-only (heh, "members"...) preview sale tonight. Adult memberships are $20; kids 17 and under are free.
And remember, Sunday is "Bag Day," which, we're told, has nothing to do with old ladies, but actually involves getting to stuff a bag full of as many books as you want for only $10. That's a hard deal to beat, so hop to it!
