There are some tricks to cut down on time wasted going from store to store for walk-in and scans. A lot of times, I find that I don't have to actually walk in to a store to get the walk-in kicks; it's enough to walk, drive or park nearby. Also, when I'm at a big store like Target, which carries a lot of variety of goods that you can also find in other stores (e.g., apparel, groceries, drinks, pharmacy, electronics, cosmetics, etc.), I'll scan the items for Target, then look at the list of other nearby stores (e.g., drug stores, grocery stores, department stores) for their scannable items, and if Target has it, I'll just scan it there. You can trick the app's geolocation down to within 1 mile, so it'll credit you kicks for scanning a CVS item at Target if the stores are less than a mile apart. Of course, it helps if you're in a densely populated area with a lot of businesses close to each other.
