Just a reminder or maybe even new information for everybody.
www.retailmenot.com is a great site for picking up coupon codes for thousands of sites on the internet, including those that sell BD's and electronics.
Just thought I'd post it for those who may not know or those who may have forgotten about it. I've been using this site for years to save hundreds of dollars.
Another one just popped into my mind:
www.fatwallet.com .
If anybody knows of others (there's some I cannot remember myself right now; I use these two a lot) post them in this thread. A google search for "coupon codes" works good too.
