RetailMeNot is an awesome site that has helped me to save hundreds of dollars online.. I know it sounds like a commercial, but it's a fact!
Anyway... B&H is kinda stingy with it's discount code, so if you don't find a discount code for what you're looking for check out http://www.resellerratings.com/
Dykmans and few others have had great success saving $$$$ with MicroSoft's http://www.live.com/
I've used it once and did save some cash, but you have to wait for the refund, etc.. and it takes a while. I guess it's a trade off if the deal is right.
