As you work your way through the store, you'll probably spend somewhat less by shopping clockwise, according to Herb Sorensen, a consultant for retailers and manufacturers. Most stores have their main entrance on the right side, and their customers tend to move counterclockwise. When researchers compared those shoppers with people who went through a left entrance and shopped clockwise, they found the clockwise folk spent $2 less per trip, on average.
The produce and floral departments are usually near the entrance, and there's a savvy strategy behind the location. In addition to imparting the message that the store is committed to freshness and health by showcasing fruit and vegetables, the scent of baked rolls is often evident as soon as you step inside as well. That stirs hunger--and more buying--according to Jim Hertel of Willard Bishop.
As you cruise the aisles, beware of "bumpouts," displays and shelves that curve or jut out. They catch the eye and make merchandise more tempting, Supermarkets are organized to slow you down so you'll buy more. The average store contains 73 product displays to stop you in your tracks.
Look above and below eye-level shelves. Manufacturers sometimes pay retailers for valuable eye-level placement. In a study by the Cornell Food & Brand Lab, researchers watched shoppers buy 40 percent of the items in their carts from shelves that were within 12 inches of eye level.
When you reach the end of an aisle, don't always expect a sale. Stores sometimes reset endcap and other high-profile displays with sale items the day before the lower price takes effect (but without the new signage). If you grab and go too early, you'll pay full price. Our reporter knows, because it happened to him.
Wherever you see offers for free stuff, make sure there's no catch. "Most purchases are a gamble," William Poundstone said. "You pay your money and hope that the product is as good as you thought it would be. ‘Free' is a great sales pitch because you say to yourself, ‘I can't regret this purchase because I got it for free.' Unfortunately, you generally have to buy something else with the freebie."
When you do pay, don't be fooled if the price ends in "9." It's a practice known as "charm" pricing. Some researchers believe that shoppers see a jar of peanuts priced at $6.99 as $6 rather than $7, making it seem cheaper. Buyers have also been conditioned to associate prices ending in "9" with a bargain, Poundstone says. "We're Pavlov's dogs salivating at the 9 we associate with a discount," he said.
Finally, at the checkout, double-check the receipt. Two percent of respondents to our survey said that they were overcharged, a figure that has been quite steady throughout the years. When an item scans at the wrong price, the Federal Trade Commission recommends that merchants offer consumers a reward, such as giving them the item for free if there's an overcharge. Some chains do so, but you may have to complain forcefully. Report frequent pricing mistakes to the FTC, your state attorney general, or your local consumer affairs office. Repeat violators can be fined.
Bottom line. If you're unhappy with your store, fire it and look at our Ratings for a good alternative. Though each has its limitations, Costco, Trader Joe's, and Whole Foods are high-rated stores available to many people across the U.S. Wherever you shop, save a bundle by using the tactics we've outlined.
