What is servings per container?

Quite simple, really. On the back of most food items, you will find something called "Nutrition Facts". Lets say you have a bag of Pretzels, and You look on the back and it says: "Suggested serving: 47 pretzels" and then , right below it, it would say: "Servings per Container: 897". That means that there are (897*47) 42, 129 pretzels in the bag....now where can you get a bag of 42,129 pretzels?
