Bookpool has got to be my favorite store for buying computer books. The prices are unbelievable. 40% or more off in many cases. If you buy technical books, you really should be shopping here.
They have the kind of savings all online stores should have. I can actually order a SINGLE book and get it for less than retail price-- with shipping and handling included, mind you! I just ordered a $30 book which they had priced at $19.95. Shipping was $3.14 which means I saved $6.91 off the retail price. Didn't have to pay tax either since it's an out of state order. Very nice indeed.
