Nearly every seller on this roster sells a commitment discount, and the pitch is always the same: pay for longer, pay less per month. What the pitch omits is the other side of the trade — a fixed price is only a saving if prices do not fall underneath it. This desk has now walked a substantial number of the same rows twice, so it is possible to say something about which way they have been moving — which is a different question from whether the advertised figure was ever the billed one, counted in the gap between what is shown and what is billed.
Which way they moved
Across 53 sellers and 90 re-read rows, 67 figures were lower on the second reading and 23 were higher. The median move was 17% downward. The largest single fall was 79% and the largest rise 101%, so the range in both directions is wide.
What a year-long plan actually buys
A twelve-month plan converts a variable price into a fixed one. In a market where figures are rising, that is worth paying for. In one where the observed movement has been downward, it transfers the benefit of any future fall from the buyer to the seller — and does so for the longest period the seller can arrange.
The scale is easy to put a number on. The median billed rate for injected semaglutide across the 432 figures recorded here is $179 a month, read September 2026. A 17% fall on that figure is about $30 a month, or $359 over a year — which is the same order of magnitude as most of the commitment discounts on this roster, and it runs the other way.
The asymmetry nobody prices
There is a second asymmetry underneath the first. If prices rise, a buyer on a monthly plan can move to a cheaper seller — the spread between sellers for the identical product is wide, which we set out in what a GLP-1 actually costs. If prices fall, a buyer on a twelve-month plan cannot. The commitment removes the upside and leaves the downside in place.
Against that, the discounts are real and often large, and most people do not stay on treatment long enough for either scenario to play out — four in five stop within a year, which is the finding in what people who quit say. A commitment that outlives the treatment is the commonest way this trade goes wrong, and it has nothing to do with price movement at all.
The practical version
Ask what happens to money already paid if you stop, and treat an unanswered question as a no. Most sellers here publish nothing on that point, which is the gap counted in the headline is not the bill. A discount that cannot be exited is not a discount, it is a price with a lock on it.
