If you live in driving distance of a Newbury Comics, you might also want to check out the Bull Moose chain in Maine and NH (Portsmouth and Salem.) All books are 35% off (even special orders) and they have graphic novels. Amazon's discounts seem to have gone way down lately, and 35% off beats them for a lot of trades now, especially if you buy in NH which has no sales tax. They also have used stuff, and you can find some great deals. I got Sweet Tooth vol. 6 in perfect condition for 4 bucks!
