Colorado Mills, Eddie Bauer has a "survival kit in a bottle" for $12.99. They're in the clearance section.

Has more in it than the one's I've seen at the sporting goods places.

Not a bad add on, or start to a BOB.

Comes with:
Bottle
Small Multi-Tool
Matches
Signal Mirror
Poncho
Em. Blanket
Whistle
Duct Tape
Small First aid kit
Flash light & Batt.

Similar to this kit, the one pictured is a much older version.
