As an AI language model, I do not have access to the latest pricing information.

Costco's bread flour is known for being high-quality and is often recommended by bakers for breadmaking. It has a protein content of around 12-14%. Costco also offers organic bread flour options for those who prefer to use organic ingredients in their breadmaking.
