Where do they get cashews that cheap?
They said Walmart is the source... so off I go!

Based on the nutrition label the container has 4,320 calories at about 10 dollars.
So 1 dollar for 400 calories, or .25 for 100.
But given they reference walmart and USDA it's very likely these are not accurate outside the US.
