Call ahead and ask if they'll have any in stock. If not, ask if they do a web order. This will allow them to charge you, and directly ship to your house from the factory. They may or may not do this outside of the U.S.
If that fails, order right from Bose and they will do the shipping straight to your house.
They're great headphones. Designed for canceling out ambiant white noise. Jet engine noise, road noise while driving (as a passenger!), dorm rooms... while listening to music most people cannot hear anything else. Using them as noise cancelling headphones (ie. with the cables unattached) you can still hear things but they are muffled, you can still hear voices, but it makes a big difference.
Try both the QC3's and the QC2's. Some prefer the around the ear fit rather than the on-ear fit. The QC2's use an alkaline battery, QC3's use a rechargable Li-ion (20-25 hours of use roughly).
