Each of these buckets claim to keep four people fed for 72 hours. They also claim to last for 25 years if properly stored. I haven't done a cost breakdown (and I probably won't bother to be perfectly honest...) but it does seem a bit spendy. But to be able to exchange a fist-full of worthless FRN's for a ready made kit seems to me to be a very good idea.
Other stores have similar items available on-line. Costco, for examples has a whole section of their food page dedicated to storage food. BJ’s has a smaller section. Neither have any of their storage food available in-store.
However you get it (provided it’s through legal means) you should lay in a supply of food to keep you going in the event on “unforeseen circumstances.” It doesn’t have to be a full scale SHTF catastrophe. An extended power failure, as but one example, will shutter the grocery store. If your cupboard’s bare it won’t refill itself particularly if the stores are closed or the normal supply lines are disrupted.
