Costco is much more than just a supermarket; for many, it's a paradise of wholesale deals. But behind its attractive prices, the store uses clever tactics to make you end up spending more than you planned. Even if you think you're careful with your money, you've probably already fallen for some of these strategies.
Entrances that surprise you
As soon as you enter Costco, you're greeted by expensive products: huge TVs, top-level appliances, and sparkling jewelry. This isn't a coincidence. By showing high prices first, your brain compares, and regular items seem cheap in comparison.
So, what you came to buy seems like a bargain, even though you're actually spending more. This first impression sets a pattern: everything that follows is perceived as a "good deal," and your cart starts filling up before you even notice.
Limited-time offers and FOMO
Costco knows how to play on the fear of missing out, known as FOMO. Signs like "Limited time only!" or "Deal of the day!" create urgency. Even if you only wanted to buy toilet paper, suddenly you end up taking dozens of soaps, cookies, or canned goods.
The truth is that many of these products will be back soon, but meanwhile, your impulse not to miss the deal fills your cart. This technique works because it makes your brain prioritize what's immediate over what you actually need.
Free samples: the irresistible strategy
A small tasting stand can change your entire visit. You walk by with no intention of buying, try a bite, and suddenly your cart includes frozen dinners, cheeses, or snacks.
Samples increase sales of those products by up to 30%. In addition, the friendly staff reinforces your purchase decision. It's simple, but it works: your brain associates immediate gratification with the product and ends up buying it.
Membership and an environment designed to make you spend
Paying for the membership not only gives you access to low prices; it also makes you want to "take advantage of it." If you've already invested $65 or $130, you unconsciously feel you need to buy more to make up for that investment.
In addition, the store's environment is designed to make you lose track of time: long aisles, even lighting, and no windows or music to set the pace. The more time you spend exploring, the more products you discover and the fuller your cart gets.
