I should have got it for free but my plan failed. If you have a MicroCenter store in your area they are offering $ 100 mail-in rebate on all xbox systems. They also are offering $ 200 off of anything in the store if you sign up for vonage. So you could actually get a core system for free or a premium system for $ 100. My mom bought my brother a system for x-mas but I decided not to get one because it wasn't free. You see they also offer a visa credit card with 13,000 free in store points but I didn't get approved for the card. One catch I'm not sure about though is that I think in order to "cash out" these 13,000 points, which is some how $ 100, you have to spend at least $ 399 on the card. Well, when you sign up for vonage it is an instant discount so you would only be spending $ 199 and then getting $ 100 back once you mail in the rebate. So, you might have to spend an extra $ 200 just to get the $ 100 back from the credit card. So I guess if you buy an extra controller and two games you could actually end up spending a total of $ 200 for the whole package.
I still need to go back and get mine but unfortunately I am already with Vonage so I need to find a way to cancel so I can re-sign up and get my $ 200 instant discount.
