Gluten intolerant over here too. I avoid gluten containing personal care products as well.
Basically you need to hit up well stocked health food stores or regular grocery stores with a gluten free and/or organic/natural food and health care aisle. You will not find a lot of stuff in Walmart.
Buying online can work out well. You can take your time and read the labels, research unfamiliar ingredients, and buy in bulk when things go on sale and the best part is nothing spoils. I buy a lot of my health/hygiene and supplements from Swanson, which carry a wide range of brands. If you spend $50 shipping is free and they don't charge sales tax. Their site has features that allow you to actually search by health concerns http://www.swansonvitamins.com/
