I remember learning about this concept first hand years ago working in a grocery store. I was in charge of stocking the freezer at the time. We had a sale on for breyer's ice cream. the 500ml tubs. they used to come in packs of 5 on the pallet. Then one day they dropped the size to 473ml and started shipping 4 in a pack for the same price. I remember this vividly because i had to completely rearrange the shelves so the new containers fit properly. Also, somewhat related, the same year dairyland stopped putting handles on their 4 litre ice cream pails. The little old ladies freaked out. Turns out, nobody likes the ice cream, they just wanted the bucket with the handle. I remember asking the dairyland driver why they took the handles off. He said someone figured out the company would save 1¢ per bucket if they removed the handles saving them over a million dollars a year or something. I still wonder whether the drop in sales from people annoyed at the loss of the handle countered the savings of removing the handle.
