Why one is cheaper than the other
Factor by factor, with both stores’ data
PromoFarma costs 170 % more per capsule than All other stores (€0.300/capsule against €0.111/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).
| Factor | PromoFarma | All other stores |
|---|---|---|
| Capsules per pack (median)All other stores 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. | 60 caps. | 100 caps. |
| Median rating at the storeBased on 6 reviews at PromoFarma and 141 at All other stores. These are the store’s own ratings, which is judge and party: they help spot a product that arrives damaged or tastes awful, not decide which formula is better. | 4.7/5 | 5/5 |
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.
