For Xbox 360 I got 2 wireless adapters and Xbox Live Gold Kit 12 Month for $115...

[Scholarly_Sam]

All of that for only $115. Normally that would cost $270.

But I traded one of the wireless adapters into Wal-Mart for a $100 gift card so really I only spent $15 on one wireless adapter and the Xbox Live Gold Kit which came with a bunch of stuff...

The wireless starter kit is $70:

The wireless controllers are $50 each:

Your math is bad, it would be $170, not $270 for what that's worth.

Returning items to WalMart for store credit is heavily frowned upon on CAG.

To prevent this from turning into a flame-fest, I'm closing this right now.
