So for the first time in my photography career, I am going to buy a camera entirely with my own money. I'm looking to buy the D300s from Amazon...I notice it says there is no tax...However I had been talking to a photographer who had recently bought a 400mm F/2.8 and he said he had bought it at a certain time because he "wouldn't have to pay taxes on it until the next quarter." I'm no accountant...So my questions to the more experienced out there...What taxes am I going to have to buy if I buy this camera from Amazon? (Which is $1799.95 with $9 shipping or something along those lines). Thanks!
