Some grocery stores actually cater everything around the “Grab and Go” shopper. The type that needs to get in and get out and doesn’t care about the cost. These end of aisle displays are meant for convenience in shopping. The same Oreo and milk grocery store by me always has milk, eggs, and butter by the cash registers. It’s brilliant, it saves you time, possibly reminds you of something you forgot and it removes the products from the competitor products so you can’t make a good judgment on whether it’s the cheapest option for you!
