I purchased a new Canon 70-200 2.8 ISII about six months ago. The day after I received the new lens, the price dropped by $100 so I sent B&H an email. Within 24 hours they gave me the discount. With this lens I got a percentage back that I plan on using very soon.

I am pretty sure this website is funded from the links to B&H, Adorama and others. The free information I get from members on this site is hard to put a price on.
