There is no rhyme or reason that I can see when they do. They can go for a year without one or have four one year. If you choose to buy from OCF, we will get you the best prevailing price on the unit you want and depending on their small discount to us, pass a few percent on to you as well. Your unit will be shipped to you by Vitamix so they will have your name, address and you will have a registration number from them, which is important if you should ever have a warrantee issue. If you need help choosing a unit that will create PEG compatible blends we can help. Your order will need to be called into OCF not done in the online store, at 949-723-4400.
