It’s no wonder retailers focus on ways to entice consumers to buy on impulse. The effort of strategic placement, pricing and arrangement of items pays off in a big way at the checkout stand. The C&E Buying Group estimates that about 40 percent of all consumer spending is made on impulse, or by unplanned purchase. This can be as innocent as grabbing a soda at the gas station or as elaborate as booking a cruise online. Motivations for these buys vary -- boredom, fun, emotional pleasure, distraction -- but 88 percent of consumers purchase items on impulse because they think they’re getting a bargain. Consumers can't resist a sale. Say goodbye to six of the biggest offending impulse buys. No matter their price, buying these items impromptu is a bad idea for your bottom line.
