According to Business Week, shoppers in the self-checkout line spend 45% less on impulse items - magazines, gum, and candy bars - than their counterparts waiting for a checker to ring things up. Apparently, people checking out their own groceries are too busy scanning and bagging to notice all the goodies and fascinating magazine articles within reach.
45% is an impressive savings! If you or other people in your shopping entourage are susceptible to last-minute treats by the checkstand, consider checking your own groceries. It's usually faster than waiting in line for a cashier, and it may be a painless way to save a few dollars every time you shop.
