Incidental merchandising involves strategically placing and promoting additional or complementary products near primary items to encourage impulse purchases. This tactic capitalizes on customers' spontaneous buying tendencies, enticing them to add extra items to their intended purchase. Retailers strategically position these incidental products in high-traffic areas or near checkout points to maximize visibility and increase the likelihood of impulse buying. Incidental merchandising aims to enhance sales, drive revenue, and optimize the overall shopping experience by offering customers enticing supplementary options.
