Site sponsorship
Proof of Purchase is sponsored by JIJ Web Solutions. This support helps operate the website and does not determine which findings are published or how products are rated.
Product links
Some reviews may link to the exact product listing used for a purchase. A link is normally provided only when the tested product is considered a reasonable buy and the listing can be identified. Products that fail important claims are not rewarded with a purchase link.
Affiliate links
If an affiliate link is used, the review will identify it clearly near the link. Proof of Purchase may earn a commission from a qualifying purchase at no added cost to the reader. A commission does not change test results, conclusions, or the price paid by the reader.
Advertising and sponsored content
Paid advertising, sponsored content, or paid placement will be labeled. Advertisers and sponsors do not receive advance approval of independent reviews and cannot pay to remove a documented unfavorable result.
Provided products
A product received without charge will be disclosed on the review page and handled under the Product Submission Policy.
