One of the downsides to eating gluten free is that you can’t eat the samples at Costco. 
In fact, I don’t even bother looking at the samples anymore. I just blow through the store, sticking to my list, like a good little shopper.
On my last visit, I was on a mission when I rounded a corner and practically bumped into a sample table. I said my typical, “No, thank you!” to the sample person’s offer, without even looking at the product, when my husband said, “Karen, I think you can eat this one!” On the table was Mary’s Gone Crackers gluten free crackers with Sabra‘s gluten free hummus on top. It was very tasty, so next time I was in a regular grocery store, I picked up some. It was kind of popular. I bought it yesterday, and it’s already gone! Next time, I guess I need to buy it at Costco, then I’ll be set for a month!
