Fatbrain is an online technical bookstore. After I placed an order there, their representative, Mr. David Civelli <[email protected]>, contacted me to arrange for Caltech personnel to receive a discount when ordering. It is not clear to me why he thought I would be the person to arrange such a thing.
In any case, if you use the referral code Caltechdisc when you order, you should receive a 10% discount on items which aren't already discounted, and free expedited shipping.
Go to Fatbrain and place your order.
