With the exception of the BBS set in November (didn't know we could order from the American site up here/dollar wasn't so high either), I've ordered all of my Criterions from Amazon.com.
I was hemming and hawing about Monterey Pop for awhile, holding out for the B&N sale, but when I saw Amazon.com dropped it, I figured I'd better order it now, as I can't depend on the B&N sale, and my mom now wants her own Nook Color, in addition to buying one for me.
Criterions are addictive.
