Costco does not want you to know this secret

The video leverages curiosity by hinting at a "secret" that Costco doesn't want customers to know, combined with the popular appeal of Costco and money-saving hacks. The demonstration of a tangible benefit (discounts and free shipping on a wide range of products) makes the information valuable and shareable.

The video reveals a "secret" Costco program called Costco Next, which allows customers to buy discounted items directly from suppliers, including e-bikes, electronics, and kitchenware, with free shipping. The creator found this information by searching "Costco Next" on Google and signing into their account.
