Have Fun Items Throughout the Store

Researchers from New York University and University of Pennsylvania found that when people put a healthy food item into their grocery shopping cart, they become much more likely to select a fun food item next. In choosing the fun food item, they're still interested in the nutritional value, but from the opposite point of view. They might very well be selecting the fun item because it's not nutritious.
     This sort of thing is true for all kinds of merchandise beyond food items and for ecommerce as well as store purchases. A shopper who makes a good, sound purchase decision is ready to buy an item that's mostly for fun. And when your customer is looking around for fun items, you'll want to be sure you make those items easy to find.
     The best way to do that is to have fun items displayed throughout the store and throughout the website. More than this, whenever a customer makes the decision to buy a highly sensible item, offer them a follow-on sale of a fun item in the same or a related product category.
     The reason to offer the fun item in a similar category is that shoppers like the items in stores to be arranged with some scheme. But shoppers also like variety within a product category, and the fun items certainly can add variety. Researchers from Columbia University and University of British Columbia found that the sort of variety provided by fun items even helps customers in crowded stores to feel better about their shopping experiences.
     For each of your product categories, what are some items you can include that are there mostly because they are fun to have, or even just fun to consider purchasing? How can you display those items to project the fun, the excitement, the humor?
