15 Things You Didn't Know About Sam's Club Slideshow

Americans love their Walmart and their big-box warehouse stores, and Sam's Club, which is owned and operated by Walmart and named after its founder, Sam Walton, combines the best of both worlds.

A team of 65 to 100 professional tasters at the "Sensory Lab" inside the company's Bentonville, Ark. headquarters tastes four different food items every day.

If you don't want to roam around the store looking for specific items, you can order them online and have them shipped to your nearest store for free.
