The market

70 of 383 sellers publish a price that survives checking

Every seller in this index was read on its own checkout, and the figure it advertises was compared with what the card is actually billed over one calendar month. Most advertised prices do not survive that comparison.

The answer

219 of 383 sellers — 57% of the market — advertises less than the card is charged. 70 advertise a figure that fails none of the checks below: it names a dose, it is billed on a calendar month, it carries no compulsory extra, and it matches what the checkout charges.

What a price fails

These are separate tests, not categories. A seller can fail several at once, so the counts overlap and do not sum to 383.

Each figure is recomputed from the dataset every time this page is built. The method is at how we verify, and the whole dataset is downloadable.

The sellers that fail nothing

70 sellers advertise a price that is also what the checkout bills, for a named dose, on a calendar month, with nothing compulsory added. The cheapest 25 are below.

What this is not

None of these findings is a claim about a seller’s medicine, its pharmacy or its care. A price that fails a check is a price that is harder to compare, not a seller doing something wrong — a 28-day cycle is a legitimate way to bill, and a starting-dose price is a real price for the starting dose. What the checks measure is whether the number on the marketing page is the number you pay.

Every seller named here links to its own page, where the figure carries the date it was read and the checkout it was read from. If a price has moved, the correction goes in corrections and the page is rebuilt.
