Your best bet imo, is to skip buying from a store, since it seems you already know what you want. Whatever hotel you are staying at, order it a week in advance and have it delivered to the hotel. You will spend on shipping... but not near as much as you will save by skipping sales tax and the b&m markup. I have done this before, it isn't a problem. Just remember to call the hotel and tell them to expect a package for you.
