Affiliate Disclosure: How The Perk Index Is Funded
As an Amazon Associate I earn from qualifying purchases.
The Perk Index participates in the Amazon Services LLC Associates Program. When you start a membership through a link on this site, we may earn a commission. This costs you nothing extra. It is how the site is funded.
That one sentence is the whole arrangement, and it is short enough to be worth unpacking. The rest of this page explains which links earn, what a commission cannot change, and the rules this site holds itself to.
Which links earn a commission
Only the links that lead to an Amazon membership earn anything. They point at Amazon under our own Associates identifier, so Amazon can tell the visit came from here. Every one of them sits on the page as a button or a plain link, and none of them is dressed up as editorial.
The rest of the links on this site are ordinary. A link to another guide, a definition, or a comparison earns nothing. There is no paid placement anywhere on this site.
What a commission cannot change
Commissions do not influence scores. The TuesdayScore is computed from documentation under a fixed checklist, one point per criterion with no partial credit, and that checklist is public.
Every membership link points to the same retailer under the same terms, so there is no financial advantage in scoring one perk above another. A perk that scores low is not a perk we earn less on. We earn the same on all of them, which is exactly why the score is allowed to say no.
A page that tells you to wait earns exactly as much as a page that tells you to join. The page willing to say skip is the test of the rule.
What this site does not accept
No brand pays for a mention, a score, or a position in a list. We take no paid placements, no sponsored posts, and no affiliate relationships with any retailer other than Amazon. If that ever changes, this page will say so first.
What we do not claim
Prices, terms, eligibility rules, and perk availability are set by Amazon and change without notice. The date on a page describes when it was last checked, not a promise about today. Where a number actually matters to your decision, the authoritative version lives on your own account, and the guides point there instead of printing a figure that will age badly.
This site also describes published terms rather than a personal trial. The method is documentation, checked on a dated pass, and the date tells you when we looked.
