Price for 70D
Two days ago I had my local Best Buy match Gearshop dpreview's store price of $1299. (for the Canon 70d 18-135) Customer service stated a couple of places that they match only. It happens that this web site is an Amazon service so since I had to sign in using my Amazon I.D. they matched it. I would remind you though I had forgotten the tax difference. If I had bought the camera online there would have been no taxes( $78) with free two day shipping. But I like to buy local ( easier to return and if there are any problems much quicker to solve) so the taxes weren't an inconvenience.
I also try to buy at BB if the price is the same as Amazon. I've gotten 3 tablets and 2 smartphones there in the past 6 months. However, I would probably buy the camera at Amazon. The reason is that Amazon's return window for a defective camera is 30 days, while the return at BB is only 15 days. I can easily completely test a tablet in a couple of days and use it a lot during the 15 days, but I wouldn't get as much test and use time for the camera. I would rather have the 30 days to completely test the camera.
As far as sales tax, I have to pay it on Amazon because I live in NY.
