Arturo Barrantes, a finance expert who hates seeing bad offers online, built a Black Friday Calculator using Omni Calculator’s platform. His tool looks at the 9 most common discounts to sort genuine deals from bad ones.
Some deals are just math traps designed by shops. Nobody wants to do the calculations when a super-mega-limited offer appears. That’s why I built this tool to help you make better decisions under pressure.
