Corrections
Last updated 4 September 2026.
Every correction this site makes to a published figure is logged here: what was wrong, when it went up, when it came down, and what it says now. The log is not pruned.
The log
Nothing has been corrected, because nothing has been published yet. Every provider figure currently on the site is placeholder scaffolding, marked as such on the pages that show it, and placeholder data being replaced is not a correction. The first entry here will be the first time a real published number turns out to be wrong.
How to report one
Write to editor@nadcost.com with the page, the figure and, if you have it, the seller’s page showing the right one. Every price on this site carries the date it was read, which usually settles it in a minute.
What counts as a correction
A wrong price, a wrong dose, a wrong milligram total, a division that does not check out, a commercial relationship described wrongly, or arithmetic of ours attributed to a seller. A seller changing its price is not a correction — that is a re-read, and the date on the page moves. A seller asking us to use a different figure is a lead to re-read the page, not a figure to publish; the record gets re-walked rather than patched.
