Compare the Same Unit
Price comparison works best when each product is converted to the same unit price. A larger package, multi-pack, or sale label can look cheaper until you compare the price per 100g, per 100ml, or per item.
| Package label | Suggested comparison | Good for |
|---|---|---|
| 500g pack | Price per 100g | Food, coffee, powders, and dry goods |
| 750ml bottle | Price per 100ml | Drinks, skincare, and cleaning liquids |
| Multi-pack | Price per item | Batteries, masks, stationery, and supplies |
Use the Final Price You Expect to Pay
