How many clicks of your mouse do you think are required to buy something on Amazon.com? If you’re a first-time buyer, meaning you haven’t created an account and haven’t provided your shipping information, the answer is 10. That’s actually a lot, especially when you take into account the “three-click rule” of web design. A few clicks can be bypassed if you search for the item rather than navigate the menus, and a few more if you let your web browser auto-fill your information. If you’re a regular, then, the number of clicks is closer to 5. And, of course, if you have an Amazon Echo device, then you need exactly zero clicks to buy something.

The point is this: retailers are constantly trying to reduce the distance between them and your wallet. Upon first glance, the most obvious difference between buying something online and buying something at a brick-and-mortar store is that you don’t need to walk into a physical store, meaning you don’t have to interact with sales reps who may or may not nudge you towards a particular purchase, or cashiers that pressure you into buying something on top of what’s already in your cart, or the physical store itself, which is meticulously designed to subconsciously manipulate you.
