Bargain or waste of money? Consumers don't always agree

In a study published in the Journal of Marketing, Erica Okada found that consumers who have bought an older model are similarly hesitant to upgrade to a new version, even if it offers enhanced features. This is because they incur a psychological cost when closing their mental account of previous consumption.
