I have shopped at the Natural Food Warehouse, Crabapple and Houze Rd (Silos center) on a regular basis for over a year b/c it is in the same shopping center as my functional wellness doctor and b/c they sell many things that my husband and I diet-wise are able to eat, but lately they are always out of the things I look forward to buying there (I think they should be aware of their best sellers and keep them in stock.). When I presented my two Groupon $30 coupons, they made me use the groupons separately although I bought more than $60 worth. I found this petty and irritating and ended up having to pay out of pocket with cash b/c one order was a little over $30 and they don't take credit cards under $5. The store has put a bad taste in my mouth and I may not shop there again. Thanks for letting me vent!
