TOTALLY got our class book for SEVEN BUCKS!
Okay, so it was $11 something after shipping.
But hey, that's still like...15 bucks cheaper than buying it anywhere else.

So thanks to bigwords.com and a few other book searching sites...

eBay has it for $6.60
A1Books has it for $21.13 if you use a .edu email
Abebooks has it for $22.95
Half.com has it starting at $23.13

All plus shipping.
