Hertz - E-Rewards & Hertz

Has anyone out there claimed a Hertz reward through E-Rewards? Are there any restrictions?

I'm getting close to claiming a $100 reward, but I'm wondering if it has some clause like "good on $1000 minimum rental" and whether the smaller rewards are 'more' flexible.

Of course, in my dreams, it will be just a plain $100 Hertz certificate that I can spend however I want. But is that just a dream?

Thanks,
