Free tickets to the Long Beach Grand Prix

This sounds a little complicated, but if you like Coca-Cola products, Champ Car racing and am/pm stores, here's how to get free tickets to the April 13 events for the Long Beach Grand Prix.
Go to am/pm. Buy two 1-liter bottles of any Coke product. Then pick up a voucher near the checkout stands for a free ticket to all the action on Fast Friday, April 13.
The vouchers can be redeemed at any Toyota Grand Prix of Long Beach ticket office location any time through April 13.
Additionally, Coca-Cola, am/pm and the radio station Power 106 are promoting a sweepstakes to win a Toyota Tundra. Fans can enter the sweepstakes when they attend the Grand Prix of Long Beach.
Fast Friday includes practice and qualifying sessions for the Champ Car World Series, Toyota Pro/Celebrity Race, Champ Car Atlantics, American Le Mans Series and the SPEED World Challenge GT, as well as the first round of action in the EZ Lube Team Drift Challenge.
The free ticket also includes a driver autograph session and admission to the Tecate Fiesta Friday concert at 6 p.m. starring Enanitos Verdes.
