Every price list on the internet is a photograph. This one included. The interesting question is how fast the thing being photographed moves, and that can only be answered by going back and looking again — which this desk did, on 53 sellers, covering 90 separate price rows. It is the one measurement a reader cannot take for themselves without doing the same work twice, and it changes how much weight any figure on a comparison page deserves.
Most of them fell
Of the 90 rows re-read, 67 had gone down and 23 had gone up. The median move was -16.7%, so the typical change was not a rounding adjustment — it was a meaningful cut. The extremes ran from -79% at one end to 101% at the other, which means a single seller’s figure both halved and doubled somewhere in this set.
A market where most published prices fall between two readings is a market under competitive pressure. That is good news for a buyer and bad news for a price list, because it means the list is wrong in a predictable direction: too high, more often than not.
What this is not
These are not a random sample. A seller gets re-read when something prompts it — a figure that looked stale, a page that changed, a review being written. So this describes the rows this desk went back to, not the market as a whole, and the true rate of change across all 475 rostered sellers is unknown.
It also says nothing about which direction any particular seller will move next. A price that fell -79% between two readings is not on a trend; it is a business making a decision, and the next decision is not predictable from the last.
What to do with it
The practical rule is short. Confirm the figure on the seller’s own page on the day you order, not from any list — including this one. A quote more than a few weeks old is more likely wrong than right, and the direction of the error usually favors you.
The second rule follows from what a changed price does to everything attached to it. A seller that moves its headline may not have moved its dose ladder or its billing interval, so a re-read should cover the terms as well as the number — the questions we keep in what they leave open. And where a figure has changed twice, the useful conclusion is about the seller rather than the price: see what sellers will not tell you for the disclosures that tend to move with it.
Every figure above is computed from this site’s own re-reading record at the moment the page was built. The most recent reading in the corpus is September 2026.
