Divide the delivered price by the verified number of servings. Compare both the unit cost and the amount you must pay upfront.
Write down the full purchase price
Start with product subtotal plus shipping and tax, less any discount actually applied. A crossed-out price is not part of your payment. A bonus book is not a reduction in cash spending unless you would otherwise buy it and have a reason to value it that way.
Keep one-time and recurring terms separate. If an introductory price requires a later charge, record that commitment alongside the initial payment. The checkout should make the terms clear before you place the order.
A worked hypothetical comparison
| Item | Product A | Product B |
|---|---|---|
| Delivered price | $60 | $72 |
| Servings per bottle | 30 | 60 |
| Cost per serving | $2.00 | $1.20 |
Product B has a lower cost per serving in this example, but requires $12 more upfront. This example does not compare ingredients, quality, safety, or results. Lower cost does not establish that either product meets your needs.
When not to calculate cost per day
If the serving size or directions are unknown, stop at the cost per bottle. Do not assume one capsule a day because another brand uses that schedule. Do not use an experimental study dose to estimate a product’s intended daily use.
For Visiflora, the supplied image supports an image-based package comparison, but a readable current label is still needed for a reliable cost-per-serving calculation.
Consider the amount you will actually use
A larger bundle may lower the unit price while leaving you with unwanted bottles. Ask whether you have used the product before, whether the expiry information is suitable, and whether the return terms apply to the entire bundle. Do not use a promised improvement timeline as a reason to buy more without evidence.
Write a maximum total budget before comparing promotions. That makes it easier to distinguish a useful saving from an increase in spending. Review shipping and return conditions as part of the same purchase decision. [FTC]
Common questions
Does the lowest unit price mean the best choice?
No. Suitability, evidence, total spending, and return terms remain separate questions.
