Ok well...firstly, Best Buy doesn't sell this model. (Yes, I actually took time out of my schedule to check on the website and I didn't see it.) Secondly, I don't think this model is sold brand new, at least that I'm aware of.. Thirdly, please only post once. If you don't appreciate the time that we take to try and answer your question (however vaguely stated), then it's time to consult the person or persons that sold you the lens in the first place. Fourthly, why not go to a reputable camera shop and support local business instead of going to a big box retail store? BB only hurts the photographic industry IMO..
I hate to be the guy to lash out, but it's rather annoying to see someone with such poor forum etiquette. If we are to help, you must give us information that we can use to determine the best possible course of action to resolve your issue. Just some food for thought.
