It was free.
This is how I did it:
Found a deal on SlickDeals for Guitar Hero 50% off at Toys R Us.
Then, I found ANOTHER coupon for $60 off, so each copy was now $20 (instruments and all).
Bought like, 4 of them and went to Wal-Mart.
Wal-Mart has a no-receipt-return policy, so I just returned it saying I didn't like it.
$720 total, minus the $80 I spent on the Guitar Heros, comes out to $640.
That's enough for a TV, right? @bullpop
