My daughter stocks up on whatever she will use for her family of 5 - if she can get a deal she shares with others.
Last week she got 12 boxes of cereal, 5 gallons of milk for $1.50 at a local grocery store. They had a deal - buy 3 boxes of cereal and get milk free...she had coupons and there was a rebate. She can't use all 12 in a reasonable time so she took some to her church food pantry. The milk she froze.
You never know when the roof will leak!
