I agree with Carolyn that the official page is the best starting point. Just keep in mind that stock levels tend to fluctuate wildly during these events, so you might want to consider having your cart ready to go beforehand. Be careful about the shipping thresholds too, because those costs can sometimes eat into the savings if you are only grabbing a couple things. Before I can give more specific advice on the value, are you aiming to restock your everyday essentials or are you specifically looking for their high-demand dupes? Knowing what you are after helps determine if you should jump on the early deals or wait to see if they do a different bundle for Cyber Monday.
