The very, very nifty Sony eBook Reader has some great pricing going on right now.
First of all, you can get FREE 2-day express shipping if you buy before May 31. But even better, you can get $149 towards the purchase of eBooks with a Sony Reader purchase and registration before July 31, 2007.
I gotta say that both the tree-hugger and gadget-freak in me luuurrrvv this kind of thing!
