You're already familiar with the bulk buys that make it easy to save money at Costco. Items like Kirkland Signature's 120-count of coffee pods or the 2-liter organic olive oil from Kirkland Signature.

However, there are other lesser-known pantry products that are top-quality while they also help you keep you under budget. We scoured social media feeds to find hidden gems that Costco customers rave about and aren't the typical warehouse club finds.

From sweet s'mores to spicy ramen, these little-known items deserve a spot in your cart.
