We try to, but when you're living paycheck to paycheck, trying to find solutions to the moving target that is your wife's fibromyalgia, have a growing, energetic baby boy, sometimes you can't afford paying twice as much or more for the product that isn't sold on amazon, assuming such an alternative exists.
