I'm a bit of an impulse buyer.

The supermarkets have arranged such items close by the checkout counter, for impulse buyers, which most of us are now and then.

Customers are often impulse buyers looking for current, fun items - so pics must be good and items should be new or only tested.

However, candy, gum, mints and chocolate are prominently displayed at the checkout aisles to trigger impulse buyers to buy what they might not have otherwise considered.

Studies investigating the link between cognitive dissonance and impulse buying have shown that impulse buyers experience less cognitive dissonance when they are disappointed with their purchase.
