No coupon code, but I love love love it! I've bought most of mine off eBay and QVC. QVC has a gallon sale every June. I can only use wheat/gluten free products. When (lol) I started they only had the Pomegranate that was gluten free. They now have 613 (love the fragrance, but it's REALLY pricey and not available in the gallons). Lately I've been using their kids formulas, specifically the Apple and the Watermelon.
I think you can get their starter packs for @ $30, just remember to cancel the autoship (or push it out to 6 months while you decide).
