Buy the Smaller Package
Yep, you read that right. Some supermarkets and drugstores charge more per unit for the supersize product. At my grocery store, the price for a 200-ounce bottle of Tide worked out to $3.71 a quart; the 100-ounce bottle, $3.52. Ocean Spray cranberry juice cocktail cost $2.66 a quart in the larger size, $2.29 in the smaller size.
