When gluten-free and food-allergic shoppers find a product we like, especially a new item or one that's on sale for a limited time, we approach the store like the vintage game show, Supermarket Sweep. I admit I've used the whole "sweeping items into the cart with an outstretched arm" tactic without shame. However, this behavior can have a dark side: I’m a gluten-free food hoarder. Sometimes I forget that I should shop for what I need, and not what I just think is a good deal. If you're faced with the same predicament, these two ideas can help.
