How Dayo checks Foundayo prices
Our pricing methodology in full: where the numbers come from, what "total cost at checkout" actually includes, how often we re-check, and what we do when a price turns out to be wrong. Published so you can hold us to it.

The one number that matters: total at checkout
Headline prices are the oldest trick in online pharmacy marketing. A medicine advertised at one price can become considerably more expensive once a consultation fee, prescription fee and delivery charge appear at the final step. So the figure Dayo compares is the total you would actually pay: medicine, plus any consultation or prescription fee, plus standard delivery.
Where a provider offers several delivery speeds, we use the standard option that most people would select, and note where free delivery depends on a minimum spend. Where a price depends on committing to a subscription or multi-month plan, we record that condition rather than quietly showing the lowest possible number.
Where the prices come from
Prices are collected from the provider's own public website: the Foundayo product or consultation page, the dose selection step and, where necessary, the checkout summary itself. We do not take prices from third-party directories, affiliate feeds, press releases or provider marketing emails, because those are frequently out of date or optimistic.
Every price we publish is attached to a specific dose. Foundayo runs through six strengths, from 0.8 mg up to 17.2 mg, and prices commonly differ between them, so a single "from" price tells you very little. Our tables are built dose by dose for that reason.
How often we re-check
Every listing carries a last-checked date, displayed on the row itself, so you are never guessing how fresh the number is. Prices move with supply, competition and promotional cycles, and a new medicine's first months are the most volatile period of all.
We re-check on a rolling basis, and we prioritise a re-check when: a provider announces or ends a promotion; a reader reports a discrepancy; a provider changes its consultation or delivery charges; stock status changes; or anything about the provider's setup changes in a way that triggers a verification review.
How the tables are ordered
By price. That is the whole rule.
Tables sort on the real cost to you, not on commission, not on relationship, and not on who asked nicely. No provider can pay for a higher position, a "recommended" label or favourable wording. If our highest-paying commercial partner is the most expensive option on the page, it appears at the bottom, and if a cheaper provider pays us nothing at all, it still appears above them.
Verification comes before price
A price is only published once the provider behind it has passed our manual pharmacy checks. A cheap price from a provider we cannot trace is not a bargain, and it does not go in the table. Read the full Dayo Verified process.
What we exclude, and why
- Providers we cannot verify. No traceable link between the website and a registered pharmacy means no listing, whatever the price.
- Prices that require a code we cannot confirm. If a discount cannot be reproduced at checkout, it is not a price, it is an advert.
- Introductory prices presented as standard. First-month offers appear on our discount list with the follow-on price shown alongside; the retail list shows standard pricing.
- Bundled programmes we cannot separate. Where coaching or app subscriptions are baked in, we say so rather than pretending it is a like-for-like medicine price.
When we get it wrong
Prices change between checks, sites make errors, and so do we. When a price is wrong, we correct it and update the last-checked date rather than quietly editing history. If a provider repeatedly advertises a price that cannot be obtained at checkout, that becomes a verification concern, not just a pricing one, and the listing can be restricted or removed.
Found a discrepancy? Tell us via our contact page with the provider, the page and what you actually saw at checkout. Reader reports are one of the fastest ways errors get caught, and we act on them.
Always confirm on the provider's own site
Dayo is a comparison and information service, not a shop. We do not sell Foundayo, hold stock or process payments, and we cannot guarantee that a price shown here will be the price you are offered after a clinical consultation. The provider's own checkout is always the authority. Treat our tables as a shortlist and a sanity check, not a contract.
