How We Get Our Data

Where Does This Data Come From?

Every fact comes from the vendor's own website, read on the date shown, with the link on each product page. We last checked all 24 products on November 16, 2026. We do not test products hands-on, take payment for placement, or publish ratings, so treat vendor claims as claims.

What Gets Listed

What We Record

How We Handle Gaps

If a page shows no price, says to request a quote, or shows us prices in another currency, we say so and show no US price. Those product pages stay available for visitors but are kept out of search engines until a verified price exists. We never fill gaps from third-party review sites or estimates. "None stated" means the page we read did not mention it, not that it does not exist.

What We Do Not Do

How Reading Was Done

Pages were downloaded or opened in a browser and read by hand into a structured list, which a script checks for missing fields and sources before every build. Mistakes are possible, and prices and promotions change often, so check the official page before you buy, and tell us if something is wrong.

Order

Lists are alphabetical. On product pages, alternatives are chosen by shared job. Advertising and any future affiliate links never affect this; see our disclosure.

Refresh

We re-read every source each quarter and when a reader or vendor reports a change. Download the current table on the pricing data page.
