Yowza is right.

In the early 1990s, I used to be given $7 per day per man to feed a crew on my boat. We had to take the money and go to grocery store and buy food. So, for four, we'd get $224 per week, or about $1,000 per month. The money varied with crew sizes, and there could be as many as ten or as few as three on board at any time. But for half of the money she spent, I could feed, and feed well, four men who all had big appetites. I realize there is some inflation, but inflation should not have doudbled those costs, esp. since she can buy in bulk and seems to from the images shown.

Moreover, a supply that is purportedly a "year" of food, all grain and legumes, is less than $1000.
