This page is for the cost subdomain. It states where numbers come from, which steps may use AI, and how advertising sits next to ranking. The operator is Zer0. The same person writes the parent site.

Independence (checkable)

1. Ranking logic is published on the methodology page. Given the same inputs, the result is reproducible.
2. No affiliate links. Every outbound vendor link carries rel="nofollow" and no tracking parameters.
3. No paid reviews, no vendor-sponsored posts.

This site displays third-party advertising to cover operating costs. Advertising does not influence which SKUs are tracked, how they are ranked, or the conclusions drawn.

Where numbers come from

List prices on this site are read from dated snapshots of public on-demand tables. Pages must not hard-code rates in prose. If a snapshot is missing, the figure is omitted rather than guessed.

AI participation

Some implementation drafts (scripts, configuration, markup) may be produced with AI assistance and then run, edited, or discarded. Topic choice, ranking logic, methodology, and any judgment paragraph labelled as author judgment are written by Zer0. AI output is not published as a conclusion without a source that a reader can open.

Corrections

Email qingfengmy@gmail.com. Confirmed errors are appended with a date. Silent rewrites of a published conclusion are not used.
