Incentives aren't always announced. Usually, if you are considering purchasing or doing an add on, you can call your guide and ask if he or she will let you know when incentives are coming out. Our guide has us on a list and calls whenever there are new incentives. Usually, the incentives run for a period of time and I've seen as short as 10 days and as long as 3 months. I would suggest you call your guide for more information.
