You might be an impulse buyer and not even know it. Here's a hint. If you head to the mall looking for a new pair of running shoes and come home with two end-of-season tops, you definitely qualify. If you find yourself grabbing the cheapy offerings lining the checkout line, count yourself in. Another red flag is deal bragging, ye doth protest too much. If you feel the need to explain why you purchased something--a pair of GAP jeans, dollar spot notepad, snow globe keychain--you might be an impulse shopper.
The bottom line is impulse buying means making unplanned purchases. If you go to Target for a baby gift and walk out with any thing else (this means lattes too), your purchase wasn't on the list, thus making it an impulse buy. You might not think much of your dirty habit, but the fact is you are costing yourself way too much money in the long run. Take some pride in your paycheck and consider how this small hole will eventually take down the boat.
The best way to fight the impulse buy is to understand your own buying habits (or join a 12-step program). If you can hold yourself to a list for two months you'll be in good shape and on your way to healthy spending habits.
