Retail science. There's something of that sort. And that's because, they are cleverly designed to do one thing, and that is to make you spend money. Every detail about the store is well thought out, and the environment is never arbitrary. Take Apple Stores for examples.

The laptop screens are adjusted to the same exact 70 degrees angle, not just for uniformity and aesthetics but for, according to Forbes, to get you to adjust the screen—touch the computer and get engaged with it. People are more likely to buy products if they touch them, and this is proven in studies. What happens is, is that it creates an "ownership experience" and more brand loyalty with customers.

That's what happens in Apple Stores, as they encourage customers to come in and play around with their devices.

Of course, Apple Stores aren't the only ones with marketing tactics. There are tons of them. Men's Health lists a bunch of marketing maneuvers and store design choices that are designed to manipulate us. Bloomingdale's numerous restaurants send pleasant aromas throughout the store, increasing the amount of time customers shop and making them about 35% more likely to spend money, according to the article.

Take apparel shops for example. Men's dressing room doors and ceilings are unusually high to convey power to guys and make them buy more cloths. And then there's the unusual atmosphere with lots of props in the store, just to make you feel special as if you're part of a club.

In other ways, retailers might use the "compromise-price effect" where you pay more for a better item. This happens when they place a relatively expensive item next to one that's priced out of reach for most, persuading you to buy the cheaper one even though it's still expensive. Alternatively, they will place a cheap item no one would buy next to the one that they want you to actually buy, according to Smart Money.

So how do you go in to stores like these that are designed to take more out of your wallet than you had planned? To do so, go shopping with a plan and a budget in mind, and know these retailer tricks as much as possible. Men's Health suggests playing spot-the-retail-theatrics when you shop:

"It's a lot harder to be fooled when you're making a game out of spotting this stuff," says Stanford University psychologist Kelly McGonigal, Ph.D., author of The Willpower Instinct. "It sounds simple, but people report a lot of success when they go out like detectives looking for gimmicks."
