Questions families ask
Is the bigger pack always cheaper?
No. Compare the price per unit (per roll, per ounce, per diaper), not the price on the shelf. A bigger pack only saves money if the unit price is lower and your family will use it all.
What is unit price?
The price divided by how much you get. $18 for 24 rolls is 75¢ a roll. It lets you compare packs of different sizes fairly.
When is a sale not worth it?
When you already have enough at home, or when the sale price is close to what you normally pay. Buying months ahead ties up money you could use now.
Does the calculator save what I type?
No. The numbers stay on your phone or computer. Nothing is sent to us.
How is the app different from the calculator?
The calculator needs you to type the numbers. The StockPock app learns them from your receipts, then tells you when to buy, how much, and when to skip it.
