On the other hand, many consumers do not consider
their purchases carefully when they stand before the
shelves, and purchase products based on what interests
them immediately (Marketing, February 2007). A study
predicts that at least two-thirds of all purchases in American
supermarkets are spontaneous (Belch & Belch, 1999). Pickton
& Broderick (2001) add that, although shopping is often a
planned activity, at least 50% of purchases are unplanned
or impulsive buying – in this case caused by the interest
in the packaging design at the point of purchase. Further,
it is said that impulsive buying can be characterized by
a disequilibrium psychological condition, where a person
feels a sudden irresistible urge to purchase something
spontaneously.
