I love playing the My Coke Rewards instant win games because you don't HAVE to spend your points to play them! You can get free entries through an alternative method...and they have lots of prizes to give away.
I just snagged one of these $10 Best Buy Pitch In Cards! You can play up to 5 times a day -Limit 1 win per household. Here's how to play without using your points:
Game ends 11/30/09 - but they add new ones all the time. I've won 2 other $15 Best Buy cards in the past few months.
They also have a instant win running right now to win a gaming system package (you can only play 2 times a day for that game but can enter in the same way).
Good luck and let me know if you win!
