How to read this comparison

Rows with a reviewed merchant destination identify the exact listing observed during the audit. Static prices and discounts are not published because the site has no authorized maintained pricing feed. Verified candidates can remain ineligible for purchase buttons while seller, stock, variant, or attribution checks are incomplete. Product testing, certification, performance, and testimonial claims require product-specific primary evidence.
