The trouble with those sandwiches is they don't have a ton of calories and are a bit expensive for lunch. If I spent 15 dollars a day for total consumable supplies on this hike my cost would be 1500 dollars. But I can easily average less then 2 dollars for dinners and 2 for breakfast. If I ate only 1 of those sandwiches for every meal at REI's price not including tax or shipping it would be 450 dollars for lunch. Throw in beef jerky that averages 30 dollars a pound and it adds up.
