This is really ignorant. Maybe you can afford it...
Why did you buy a 2nd hand 7D on the forums instead of buying a brand new one from a store? If you could afford $1400 here you could certainly afford it from B+H?
To some people the extra $300 makes the difference.
I am surprised by so many people being mad, agitated etc etc.
I think the focus is the "mad, agitated" part not the price difference part.
People get unnecessarily upset about shops not honoring price mistakes, like on SD they regularly talk about boycott, BBB, class action lawsuits, etc., it's usually quite an amusement to see.
