I would extend the membership for another year after it began.First, call Costco with your questions to get correct information, and they can assit with renewal.Keep in mind, if you enjoy the Costco experience with quality products,and excellent customer service, you should be able to make the decision to renew or not.
Probably no extn, but it doesn't hurt to ask.
I believe this is a question that you should contact Costco about directly! Perhaps calling your local store will give you some insight on what their policies look like.
