Unlike a fixed monthly cost such as your mortgage or car payment, the amount you spend on groceries each month is somewhat flexible. While the common advice of clipping coupons and buying generic brands to save money while shopping is sound, by far the best way to truly keep your grocery shopping expenses under control is by understanding how grocery stores entice you to spend more than you really want.

By fully understanding the ways grocery stores encourage you to spend, many of which you probably never even noticed before, you can combat their strategies and spend money only on the merchandise you really need.

Although a grocery store may appear to be simply a place to purchase food and other household necessities, in reality it's a cutting edge example of "how to sell more than consumers really need." Since you are the consumer, it's important that you realize these sales tactics so that you walk into a grocery store to get only what you need while avoiding everything else that the grocery store wants to sell you.

You'll notice when you enter a grocery store is the mouth-watering smell. There is a specific reason why grocery stores smell of freshly baked goods, and also why the bakery is almost always found near the store entrance.

The reason is that a bakery making bread and desserts gives off an enticing smell, and that smell is likely to make you hungry. The grocery store also knows that if you feel hungry while you shop, you are likely to spend more money - a lot more - than if you are not hungry.
