I like the site you linked to, they seem to be a bit more organized than some of the other BF sites.
I'm not a big BF shopper, done it a few times, mostly just saw long lines and junk merchandise, for the most part, kind of stopped after that. I do like seeing that ACE hardware is continuing the 50% off any non-sale (other exceptions apply) item under $30 coupon though.
