The music Fast-tempo, upbeat music has been shown to influence shoppers to make spontaneous purchases. 2. The products near checkout Chips, candy, gum and sodas are placed near checkout, luring customers who think one more small purchase won't hurt. 3. Pricing More expensive items are often placed at eye-level or at the end of aisles. 4. In-store samples Engaging a customer's sense of taste is a sure-fire way to invite them to spend more money. 5.
