Do You Really Need the Shopping Cart? You enter the mall with the intention to pick an item or two and drag along with the shopping cart the moment you enter the mall. But you do not know that, it is the shopping cart that encourages you to toss more things into it. So in a way even before you have started shopping your list has increased. The way the items are placed with the most expensive products placed at your eye level and less expensive ones placed at the bottom of the shelf. Because you mostly likely to pick items that are at your eye level. And the grocery section, you will notice the in-house brands of retailers prominently displayed next to brands that have double the price for the same item. And with the motto of save money we go for bargains and grab the cheaper in-house product.
