If they can confirm that they've shipped the order, it may very well be stuck in customs.

Usually my orders from Nashbar come through in a few days but Canada Customs makes no guarantees. And neither does Canada Post. I've been waiting for two weeks for an E-bay order that I know left Switzerland more than two weeks ago. The OP may be experiencing similar stellar service once it enters Canada.

But if Nashbar can't confirm that they've shipped the order then it may indeed be a Nashbar screw-up. I've had very good luck with them, personally.
