Barnes & Noble does carry them in the store in the craft section. They start bringing in their full line of regular calendars soon, and usually have a stack of these along with their "boxed" calendars in addition to being in the craft section. If you call ahead, they will hold one for you for up to a week; you are not under an obligation to purchase if you change your mind. Also, if B&N is out of stock on them, they'll get one in for you within several days and call you when it's in the store!
Knitting is more like tying your shoes than it is like patting your head and rubbing your tummy at the same time.
