Why can't more game companies do this? Its a fun idea and I imagine some people I hand the coupon to won't have played the game before. Totally great advertising if a new Plants VS Zombies might been soon around the corner!
Oh and maybe if you used a coupon to get a copy yourself, that might be OK too? Shhhhhh, it might not just be for kids!
