Most people who shop at Costco regularly have a rough sense of what things cost, but Costodle quickly reveals how imprecise that sense tends to be. The difference between a product priced at eighteen dollars and one at twenty-four dollars might feel small in person, but in a game where you need to land within five percent, that gap is the difference between a yellow result and a green one. The feedback trains you to think about price more precisely than a typical shopping trip ever requires.
Products that seem easy to guess often turn out to be the most deceptive. Everyday staples like cooking oil or laundry detergent come in Costco-sized quantities that most people have never purchased before, which means the unit logic that usually anchors price guesses does not apply in the same way. Players who do well tend to think in terms of what they know about Costco's pricing structure rather than just the category the product belongs to.
