Yes, there is. If you found a good deal on Black Friday (as one we recommend here), don't hesitate and create the order as soon as possible.
Why? Because it may be sold out any time when the number of ordered reaches the quota limit, with no notices, and you will miss it.
But what happening if I get a better price Cyber Monday thereover? No matter! Because most providers guarantee to return your money in at least the first 7 days, so you can comfortably cancel your order on Cyber Monday, then place a new order at that better price. You may also ask the vendor to match the product price if you want.
