According to Business Insider, "Wholesale retailer Costco sells groceries, personal goods, and much more in bulk. Sometimes, Costco's giant wares are a bit entertaining. Pounds of snack food, gallons of condiments, and hundreds of candies are all available for sale." That's why Business Insider made a list of the largest portions they sell. They sell classic gum balls in 850 packs. They sell 50lbs worth of bird feed.
