It's not really a secret, but last year Best Buy had a lot of their sales online the night before (and with a free shipping code to boot), so I bought what I wanted from them (a 51" TV and some DVDs like 24 for 12.99) without getting up. The best part was that, for some reason, I didn't get charged tax on the TV, so it ended up quite a bit cheaper than going in. Best Boy is one of the most zoo-like stores on Black Friday, so avoiding that place and still getting what I wanted was great
Sears had most of their stuff online late Thanksgiving night too, but I didn't end up getting anything there.
The only store I actually ended up going to on Black Friday was Target, which is right down the street.
From reading this thread, I'm thinking that one good secret would be that, if you can't find something, look in all the washers and dryers because you might find it there, hidden by someone else :)
