Account for conditions
Add shipping and taxes if comparing actual delivered cost. Do not mix a first-subscription promotion with an unconditional one-time amount without labeling the difference.
Respect your storage limit
Use the quantity you can identify and store according to its instructions. A lower nominal unit price does not establish a product’s durability or environmental advantage.
Avoid a false saving
A larger pack may have a lower piece price while requiring more cash now or a delivery threshold. Compare total delivered spend as well as the ratio. Keep a promotional code in its own condition field and check whether it applies to the selected variant. A struck-through comparison value is not automatically a verified historical selling price, so it is not used as a saving baseline here.
Before you decide
- Compare like variants
- Include payable conditions
- Keep upfront spend visible
