1: Go to your local gas station and pick up a few papers the night before. They're packed with coupons and other hidden deals.
2: Coffee is a must have. Trust me, without it you won't be able to function for more than a couple hours. The early adrenaline of running to find the best deals wears out quickly.
3: Always eat something prior to heading out, you'll need the energy.
4: Dress warmly. Remember it's winter, and you will have to stand outside more often than not.
5: Be aggressive. Some people can get pretty competitive with things like doorbusters when there is only a limited supply, so if you want it, you're going to have to work for it.
6: A parking tip: follow the people that are carrying a lot of bags, chances are they already hit up the deals and are headed to their car to leave for the next destination.
7: Be patient. Black Friday also means a lot of waiting and a lot of people. If that's not your thing, I would suggest skipping this event and waiting for Cyber Monday.
Good luck to all the shoppers this year!
