What does the term "impulse buy" mean in a retail context?

In a retail context, an "impulse buy" refers to an unplanned purchase that is often stimulated by various marketing strategies, including strategic product placement. Retailers design store layouts and product displays to catch customers' attention and encourage them to make spontaneous purchases, rather than adhering strictly to their shopping list or prior intentions.

This term emphasizes the psychological aspect of buying behavior, where enticing displays or promotional materials can lead shoppers to buy products they hadn't initially considered. The placement of items near checkout counters or in high-traffic areas is a common tactic used to increase the likelihood of impulse buys.
