Quest Nutrition has appeared at Costco a few times in its time, and on each occasion, like many other companies in the membership retailer, it put together a larger size with better value than its standard sizes and bundles. Closing out 2025, the legendary protein snacking company has introduced another with a slightly larger box of the signature Quest Protein Bar and it saves you a good amount of money.
Typically, through Quest Nutrition’s online store, you’ll pay $33.48 for a traditional box of 12 Quest Protein Bars in a single flavor. Just landed at Costco is a box of 14 pieces of that same product, packing between 20 to 21g of protein with three flavors: six each of Chocolate Chip Cookie Dough and Cookies & Cream, and two of Chocolate Brownie. The variety is great; however, the value is even better as Costco sells it for $28.99, saving you 26% compared to that box of 12 directly from questionutrition.com.
