Costco’s website show that bucket o rations on sale thru 4/3.
I would just say to be careful in your idea of “Portion.” I have looked at those and sometimes the idea is a 200 calorie meal. That’s virtually starving as it is less than a thrid of what the average person needs to barely survive, much less “work the fields.” But it’s got some variety and it’s a starting point, I’ll give you that.
