In the recent Costco mailer, some friends and I all noticed that a "72-hour" kit that Costco carries had a limited time online discount available. The $60 kit was/is available for a limited time for $40 with shipping (Costco 72 hour kit sale), so I decided to check it out. One more 72 hour kit could be good for my family, and if it was nice, would make a great gift to give to some family members and friends.
