Save money on groceries
Not only is buying in bulk usually cheaper, it also allows for culinary innovation down the road. Often meat in bulk is much cheaper than a small amount in a single purchase, but always compare prices.
Think of smaller ingredients you can buy to turn a single bulk purchase into a totally different dish.
Also, when you buy bulk, make sure you have room to store anything. You don't want to buy a lot of meat, and then lack the freezer room for it.
