FYI. Quite a few items on their site were $4.03 this morning. Granted I didn't notice it until after I had placed an order. They seem to be a good shop, according to ResellerRatings, so I don't think they'll piss everyone off when they cancel the orders.
EDIT: *I* won't be upset should they cancel my order. Actually, I just got the e-mail stating that they've done just that. Oh well.
