Bad Choice: Buying Flour at Costco
Unlike vanilla extract, flour is a baking staple that might not be ideal for bulk buying at Costco. Prone to spoiling and attracting pests, it’s wise for occasional bakers to stick to regular-sized purchases at local stores.

While the allure of Costco’s bulk pricing may be tempting, the risk of flour going bad before it’s fully used outweighs the potential savings. By purchasing smaller quantities from local stores, bakers can ensure freshness and minimize waste.
