Are you asking what led me to create a website that focuses on affiliate links? (If that's wrong, please correct!) I decided to create a website like this because I like this type of data, and it blended naturally with the potential upside of affiliate marketing fees. I wrote somewhere on the site about what first led me to this idea -- I was buying pacifiers for my kid, and it was cheaper to buy two two-packs than one four-pack. That made me realize that you can't always assume that larger quantities have a cheaper cost. Figured it would be cool to apply that sort of calculation at a much larger scale!
