A daily price guessing game
Study the product, enter a plain dollar amount, and use each result to get closer. You have six guesses to land within 5% of the target price.
What Is Costcodle?
Costcodle is an independent daily price challenge built around product and package details. The target is a game value for the challenge, so it is not a live store quote or an official Costco service.
