Costco is selling a giant tub of macaroni and cheese and giving you 20 years to eat it.

The nearly 27-pound tub costs $89.99, contains 180 servings, and has a 20-year shelf life. It is currently out of stock on Costco's website but available for purchase on Amazon.

The pasta and cheese ingredients are packaged separately in pouches with oxygen absorbers to ensure they last longer. Customers reviewing the tub on Costco's website say that despite its long shelf life, it tastes delicious.

"Honestly, I was expecting something that tasted horrible. I was surprised to find out that it was very good," one reviewer said on Costco's website.

Costco is known for offering deals and discounts on items bought in bulk. Some are more extreme than others, however. Earlier this month, Business Insider reported on another of Costco's giant products: a 6.6-pound bucket of Nutella that it sells for $21.99.
