Sure, the Tactical Sammich can get you plenty fed with bread during the post-apocalypse. Just because civilization's dead doesn't mean you have to eat the same bread and filling combo the entire year, though. Vary your end-of-days sandwich consumption with the Candwich, a real canned sandwich.
Billed as the "perfect product for people on the go," the sandwiches come in a pop-top can around the same size as some juices I've seen at the convenience store. Of course, sandwiches are easy enough to make and pack at home, so I don't really see the point. Unless they actually mean "would-be survivors of the armageddon on the go," which makes absolute perfect sense.
The Candwich requires no refrigeration and can be kept on the same shelf as the rest of your canned stash. The Mark One website claims it "has a long shelf life," although they didn't give an exact number. Hopefully, it can stay good for at least a year and half, so you can stock up now for the inevitable fall of civilization that awaits us in 2012.
Currently, the product is only available in one flavor: peanut butter and grape jelly on a longish bread. According to the company, they're releasing two more soon, namely BBQ Chicken and peanut butter with strawberry jelly. Yum yum.
We don't know how much it costs per can, but you can get a 4-pack of the Candwich for $12 and a 24-pack for $72. No word on discounts for bulk orders (we know you're thinking a year's supply), but you're preparing for armageddon, so we doubt you care about an extra dollar off or whatever.
