MEASUREMENTS AND PURCHASE DECISIONS
Compare mixed compatible container sizes.
When can one large container plus small containers beat an all-large order?
Use the matching calculator
Use this decision sequence
- Confirm both sizes contain the same compatible product.
- Enter required liquid volume before container rounding.
- Compare every feasible large-container count with the small containers needed for the remainder.
- Choose the lowest stated purchase cost and review its surplus and fees.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| All small | Can win when the large size carries no quantity discount. |
| Mixed sizes | Can cover a remainder without buying a second large size. |
| All large | Can win when the unit discount offsets surplus. |
Worked comparison
You need 6 L. A 1 L container costs $15 and a 5 L container costs $50. Six small containers cost $90; two large cost $100; one large and one small cost $65 with no surplus.
Check before using the estimate
Use quoted container prices; no store prices are assumed.
