Grocery Stores, Laurie. Silk Soy is found in the dairy section next to the milk and the other I think only needs refrigeration after it is opened so most stores keep it with like the hot cocoa and drink mixes type stuff...
Laughing Cow now makes more flavors- I love the French Onion! The other is Garlic & Herb. I've been able to get them here in the dairyland for a long time but I saw them at Sam's Club last weekend so they should be in your neighborhoods by now.
