I dont know if anyone has posted this before, but i have an idea for a twist on the best-buy and walmart cd keys scams.
1. Go to a local walmart and or best buy and buy a WoW Battlechest.
2. Open it carefully at home.
3. Use cd keys for whatever you need.
4. A litte twist here, instead of puting things back in a hoping an excuse can work. you can demagnetize the install cd's with a large magnet from a home speaker set or any other magnet.
5. Then put things back in box take it bac to store say "cd's don't work" ask them to try it themsleves because they wont work and there's really nothing they can do. Though if they offer you just new cd's reject it and act all outraged.
6. Get new battlechest do it all again at a different store.
I've tried it twice and worked great both times. Enjoy!
