Answer 2

If you made 6 purchases at the ordinary price (12 cans) it would cost $1.98
versus the $1.74 for the lot of 1 doz. That is a saving of a whopping .24 (24 cents) for the 12 cans or a savings of 2 cents a can. Which means you may have to eventually get rid of them as they pass the expiration date!
