We are supplement retailers/researchers ... We only sell one product in any given category. Therefore instead of someone looking at B12 (for instance) and trying to decide between 3 brands, each with 4 product types ... we only sell one B12 product, eliminating confusion for buyers.
Tell us a bit about who you are and the people you reach
Health minded 'regular folk' ... nutrition nuts/over educated consumers are not interested in what we do ... we sell to average people who work 50 hours per week, have 2 kids, a spouse and no time or interest in becoming a health expert. Of course they still want to be healthy they just don't have time to become experts

The concept for these banners is more generic ... instead of product focused, these banners are targeted at people who have shopped (or at least visited our site before) and we'd love to have them shop with us again or consider us again or what are you waiting for or fill in the blank.
