At Super Saver, 4 packs costs $10, so 12 × 4 = 48 gets us the amount if cans, which we can use to calculate the ratio. The ratio will be 48 cans : $10, or 4.8 cans : $1. Shop Smart will use the same principle, 24 × 2 = 48, so 48 cans : $9, or 5 1/3 cans : $1. And at Price Busters, 12 × 3 = 36 cans : $9, or 3 cans for $1. Overall, Shop Smart has the best value per can, next coming with Super Saver, then Price Busters.
