How I test
I'm Mark Dunne. I run a supplement brand on Amazon and Shopify, and every tool here is scored against that store: at least 30 days of use before a score, prices checked against the vendor page every month, codes tested at checkout. I earn a commission when you buy through a link. It never changes a score, and I say so when a tool is not worth the money.
