You mean you never used CanonPrice Watch?????
I thought everyone on the forum used the site to check prices on Canon products, and they provide links to those prices (usually at B&H, AMAZON, ADORAMA and many other authorized dealers). Also provides historical data on past prices for several years, and even lets you create an alert at a specific price on an item you are interested in purchasing. Also includes accessories, and memory cards too.
And, they do the same at their other site, Nikonpricewatch.
Also, they are a member of the forum and contributor....
