Purchase as a replacement bowl or as a second bowl.  You may want a second bowl if you use your Bosch Universal a lot, you may find a time when your bowl is already full of a mixture, a second bowl could be handy. Or you may find a recipe that asks you to mix these ingredients then set them aside. In a separate bowl you would mix more ingredients and then you would need to combine them.
