One psychological tactic I use is anchoring, where you present a higher-priced option first to make other options seem more affordable or like a better deal. When offering a service package, I always highlight the premium package first. It includes all the bells and whistles, so it establishes the value at the high end. Then, I present the mid-tier package, which includes most of the core benefits at a lower price. Customers often see this as the "reasonable" choice, feeling like they're getting great value without overspending. I've implemented this on a pricing page for a subscription service, and it led to a 30% increase in mid-tier package sales because it framed that option as the smart, balanced choice. Anchoring works because it helps customers justify spending a little more, and they feel good about their decision.
