If you've ever shopped at Costco more than once, you've probably experienced the confusion of suddenly discovering that the layout of the store has changed slightly.

This is no accident — Costco is known for its frequent product rearrangements, but the numbered signs at the end of each aisle aren't helpful on their own.

The absence of detailed aisle labels in the warehouse makes it easier to switch things up without customers becoming too reliant on a set layout.

One of Costco's key strategies is placing commonly bought items and household staples, like toilet paper or milk, toward the back of the store.

This layout encourages shoppers to wander through other sections, potentially discovering more products worth purchasing along the way.
