Don't wait for November thinking you'll get better deals - that's the trap. By actual Black Friday week, a lot of the really good stuff is already picked over or the prices haven't moved much from October anyway. The real game is starting your searches in late September, before retailers even officially kick off their "early" sales.
Price tracking tools are solid, but here's what people miss: sign up for retailer newsletters and follow their social media accounts directly. A lot of stores drop flash sales or doorbusters on their own channels first, and you'll catch those notifications before they hit the aggregator sites. Also check if any stores you shop at regularly have loyalty programs - some give members early access to deals, sometimes even a few days before the public stuff goes live.
One more thing that saved me last year: keep a wishlist going throughout the year on whatever site you're buying from. That way when October rolls around and prices start shifting, you can actually see what's a real discount versus something they marked up beforehand and then "reduced." It's easier to spot when you've got the original price right there instead of trying to remember what something cost months ago.
