We get trapped and stick around for a while.
If someone wants to buy 100 books, but that person could only get 5, it takes a lot of time to decide which 5 books are the best. The other 95 are rejected, but since they were also good, the consumer comes back whether it would be a week, month, or year later to buy more books.
With more options, consumers have to closely examine each option. They are more likely to come back and buy more of your products.
When deciding among 10 products, a consumer may be able to make a quick decision. However, before the consumer makes a purchase, he might see another product that he wants to buy. People don’t leave, but instead they stick around. When they leave, they are sure to come back.
