Checkout Line Impulse Buys

I'm sure everyone has noticed how stores place food, drinks, and other items in the checkout lines. They put them there hoping you will be in line and impulsively buy them. Food and drinks when you are hungry, card games that kids beg for while waiting in line, and magazines with the latest news you want to read. All while conveniently placed, most if not all of these items are overpriced. If you were to look in the drink aisle you could find a 2 liter bottle of soda for 99 cents, while a 16oz at the checkout line is $1.50.  That magazine you just had to have would have been free if you signed up to the website online. And the 2 pack of pens you decided to get were just as much as a 4 pack if you checked the pen aisle. While these sales are great for the store, it would be best to check what the cheaper version is of each item elsewhere in the store.
