A page covered in struck-through prices and first-month offers reads as less trustworthy than a plain one, and it is natural to expect that it also tells you less. That expectation is testable, and on this roster it is wrong — as wrong as the assumption tested in is disclosure a trait, and in a more interesting direction.
What the comparison shows
99 of the sellers this site can rank use promotional language somewhere in their recorded pricing — a first month, an introductory rate, a code, a struck-through anchor. The other 481 do not.
On the hardest disclosure in this category, publishing a dose ladder, the promotional group does better: 80% against 28%. On stating what the price does at a higher dose the two are level at 43% and 35%, and on publishing a state list they sit at 47% and 32%.
What it does not excuse
Anything. A promotional figure is still not a standing rate, a struck-through anchor is still a number nobody has been charged, and a fifth of the pricing notes on this roster are offers rather than prices — which is the separate count in how much of this pricing is a promotion.
What changes is the inference a reader draws from the style of a page. Marketing intensity is not a proxy for opacity here, so a plain-looking storefront has not thereby earned anything, and a loud one has not forfeited it.
Where this sits beside the other cross-check
This site has run one other test of whether a seller’s behavior predicts its behavior elsewhere, in is disclosure a trait, and found nothing at all: publishing a ladder said nothing about publishing a state list.
The two results fit together. Disclosure does not travel between dimensions, and the one association that does appear has a structural cause rather than a moral one. The practical conclusion is the same as it was: check the specific thing you care about, seller by seller, as listed in the questions they leave open. Corpus read October 2026.
Science & Co identifies its lowest advertised rate as a twelve-month-plan figure in its FAQ. That qualification is a disclosure worth preserving beside the price. Whether a discount exists and whether its commitment is clearly explained are separate questions, just as the aggregate comparison above suggests.
