In theory one of your competitors in that category is paying that max percentage your seeing, on mine it fluctuates constantly from 3% to 15%. For a more competitive category those numbers might be higher, for a less competitive category lower. Personally I refuse to pay more than 3% and my sales are acceptable.. might be 5% in a more competitive category. I think there are promo seller rebates for stores, so you get some of it back.. but dont quote me on that.
