Why one is cheaper than the other
Factor by factor, with both stores’ data
All other stores costs 105 % more per capsule than Amazon (€0.205/capsule against €0.100/capsule, medians of both catalogues). That difference does not come out of nowhere. These are the data that explain it, with each store’s figure alongside: capsules per pack (median), products with declared additives.
| Factor | Amazon | All other stores |
|---|---|---|
| Capsules per pack (median)Amazon sells bigger packs, and a big pack spreads the same tub, the same label and the same shipping over more capsules. Part of the price gap per capsule is this and not a discount: comparing one store’s small pack with the other’s large one inflates the gap. | 120 caps. | 60 caps. |
| Products with declared additivesWhat the pages of both declare: anti-caking agents. An additive is not fraud, but it takes up grams that are not active ingredient and is cheaper than the active ingredient: where more additive is declared, the price per capsule drops without the product being better. | 0 % | 17 % |
None of these factors is an accusation. They are medians of what each store publishes on its pages on the day prices were collected: where a page does not declare a figure, that store does not count in that row instead of counting as a zero. A specific product can contradict its store’s median, and that is what the full table is for. How all of this is calculated.
This is a filter, not another ranking. The score that sorts this table is exactly the same as in the full vitamin B12 comparison: the only thing removed here is the products that do not meet the criterion above. How it is calculated.
