So, I have been saving money so that I can just pay cash for my 7d. My plan was to go ahead and buy it at Best Buy now and put it on the 18months no interest they have going. But the sales tax is going to tack on a significant amount of course. My simple question is, does Amazon charge sales tax. I did a google search and searched their website and it looks like they only charge sales tax in the states of Kansas, Kentucky, New York, North Dakota, or Washington. Any of you guys that bought thru Amazon able to confirm that? Any other places that I could buy and not have to mess with sales tax (besides finding a used one of course)???
