One-Click Ordering
Fun fact: The giant online retailer owned the patent for 1-Click ordering until 2017. One-click ordering has generated billions of dollars in revenue for Amazon. If you haven’t used Amazon yet (I doubt that)… one-click lets you pick a default set of billing and shipping options, so when you want to purchase something, everything it’s there, shipping the products directly to you with just one click.
This convenient and instant system of ordering encourages impulse buying. People who use One-Click ordering say they tend to spend more than they actually want to. It sounds like you’ve been tricked.
