Stacy - I totally agree about Circuit City. I may brave going there this year to if the deals are right...DH has been hinting towards a HDTV for the bedroom.
SBD - I usually just get the deals in the local paper. I used
http://blackfriday.gottadeal.com/ website last year for other deals, but I think it is more fun just digging through the paper. Some ads for BF are released the Sunday prior to Thanksgiving, others are released Thanksgiving day. It is hard to tell. Also, each of the stores websites will have information on what sales they will be having.
