Compare pack prices using the same unit

The cheapest package is not always the cheapest quantity, so put comparable products on the same measurement basis before choosing.

1. Check the actual pack quantity and the selling price you qualify for. Read conditions on promotions instead of assuming a member price or multibuy applies to a single pack.
2. Compare shelf unit prices only when they use the same measure. If necessary, divide price by quantity and convert both results to the same weight, volume or count.
3. Check that the contents are meaningfully comparable: a different concentration, drained quantity or included accessory can make a simple comparison misleading. Keep quality and intended use in your decision.

Finally, consider how much you will actually use and can store. A lower unit price does not automatically make an oversized pack the more practical purchase.
