I've heard that Nalgene is holding all of your bottles if ONE is backordered (and quite a few ARE backordered.)
If your bottles are more than 1 1/2 weeks old, you might try calling Nalgene and get them to ship all the ones you have, and get them to ship a backordered when it's available.
I thought I was getting my bottles on Friday, but didn't get them in until this (Monday) afternoon. Bottles look great..., you WILL get your bottles, just takes some time <g>.
