Height makes a big difference when it comes to product placement, with items at eye level usually costing the most. Manufacturers actually pay extra for these prime spots, and the price tag reflects that extra cost. Many casual buyers will stroll through the aisles and simply select the closest item without comparing the prices of those products above and below the pricey popular brands, resulting in big profit margins for the store.
To counter this tricky tactic, stand on your tiptoes or kneel down! Sometimes the best deals are not the ones in the middle, so search top to bottom to get the best price on products. It's also wise to compare price per unit/ounce because, while a bigger package costs more up front, it could be cheaper overall.
Also, if little ones are tagging along, keep a lookout for slightly lower shelves that are right at children's eye level in the toy and candy aisles!
