But remember, a bargain is only a bargain if you were going to buy it anyway. If you find that it's later discounted by significantly more, you may be able to buy it again at the cheaper price and return the more expensive one when it arrives. If it's a need, rather than a want, it's a good idea to buy it when you spot the discount. Ultimately this depends on how much you need the item.

If you spot something on your list, that is available at a lower price than you found in your research, then it's a bit of a gamble whether you buy it then and there or hold out to see if you can get a further discount. You can also use tools like Camel Camel Camel (opens in new tab) and Kelkoo (opens in new tab) to get alerts of discounts, and in the case of Camel Camel Camel, check historical prices of Amazon items to see how low the price has been before and when items tend to be cheapest - which may not be over Black Friday or Cyber Monday. Write a list of what you are looking to buy, where you can buy it and how much it costs before the sale. The key is to do as much research as you can beforehand and come up with a Black Friday battle plan. In general, how much money you can save on Cyber Monday tends to be very similar to Black Friday, but retailers may switch up which products they offer discounts on, and you don't always get a heads up.
