I have larger size bags, and had bought the snack size basically on a whim. To my surprise, it's turned out to be one of the more versatile sizes I own. They work well for storing small amounts, of course, but are also great for storing measured components during cooking and smaller bits for transport. Having taken salads to work for lunch in the standing bag, the snack size has been particularly useful for tucking bits (meat, cheese, nuts and croutons) into the larger bag, along with a pocket size for the dressing. It really was a pleasant surprise just how useful this size Starter is.
