I'll offer to send books to anyone at my cost, if it's in support of this task. I get 50% off O'Reilly books, and something like 20% or 30% off AWL books. Please bump in a little for shipping and tax in the appropriate states.
I take Paypal, and that's probably the easiest way to do this. Just use email@example.com as the designee, and copy me on some email so I know what the money is for.
