Steve let me make a suggestion, rather than buying from Best Buy purchase the lens from a local camera shop. The reason being is if you need actual knowledgeable input (not necessarily this purchase but in the future) the camera shop is your odds on favorite that they can give you good advice. As to price, generally a camera shop is not going to be able to compete against a big box store. However, when I was actively racing mountain bikes, and I needed a part, I would go online and see what price I could find which was 90 percent of the time cheaper than my local bike store. What I did was print of the website, add in the cost of the shipping and maybe round it up a couple dollars for the fact I could get it right now with no wait. With rare exception, the store was happy to meet my price and they got a sale that would have normally been another one lost to the internet. I do the same thing with my local camera shop. I appreciate the immediacy and them as a valuable resource; they appreciate my business as it is hard for a camera shop when most people taking pictures anymore are using Ipads or phones.
