If you ever wondered “Is there such thing as TOO MUCH macaroni and cheese”? Well, we may now have an answer. Costco just started selling a 27-POUND BUCKET of mac and cheese. That’s six gallons. It’s got 180 servings . . . and it has a shelf life of 20 years. It costs $90 a bucket, or just $2 per serving (or maybe it’s $90 per serving, if you approach this bucket like I’m going to). Unfortunately, at last check, it was sold out online.
