Here is a wonderful list of black Friday deals at a variety of stores. My strategy has generally been to order things online on Thanksgiving evening and sleep in on Friday, but some enjoy the RUSH of standing in line for hours on end and fighting for items that will be on sale the following week anyway.
Whatever your strategy is, I hope you make a list and stick to it. Impulse buying is not a way to save money and will cause a major debt in the end. A sale is not a reason to go into debt and overspend. Use your money wisely and have fun looking through the deals!
