One email a week with everything that moved: dated price changes across 106 scored research-peptide vendors, what sold out and what came back, rubric score changes with the reason, and the certificates we opened. Generated from the same append-only history the site prints — nothing typed for the email, no vendor consulted.
This is what subscribers receive, computed from this week's readings (2 Nov–8 Nov). Every line links to the page holding the evidence.
1 certificate of analysis opened and recorded this week (COA library); 60 listings read for the first time (price index).
Our price capture reads product pages once a week and appends what it finds to a history that is never edited. A daily email would repeat the same readings; a "deals" email would need someone to decide what counts as a deal. Instead the report is a diff: if a price moved, it is in; if it didn't, it isn't. Partners and non-partners are listed on the same terms, and where a partner code applies it is printed beside that vendor's line with the disclosure. If one compound is what you watch, sign up from its compound ranking: the welcome email then links that compound's ranked vendors, and every move on it is in the report.

Twice a week, Monday and Friday mornings US time, each on readings taken the evening before. A daily email would have nothing new in it. If a week has no changes, the email says so in two lines and stops.
Partner sales first: every struck-list sale at a scored partner, read the evening before, ranked by how far the price sits below the market median for the same vial across every vendor we track, with our code applied. Then only what changed, with dates: every price move on the listings we track (vendor, compound, size, old price, new price), listings that sold out or came back, and certificates of analysis we opened. It is generated from the same append-only price and score history the site prints, so nothing in it is typed for the email.
The deals section is partners by definition: it is where we hold a code or a link, and every card says so. The price-move sections list every move at every scored vendor, partner or not, in order of size. Rubric scores are computed without reading partner status, and the affiliate relationship is disclosed in every issue.
