Question about BlockBuster Online

I want to do BB Online as an offer, and I was wondering, if I use a code that gives the first month free, would I still be able to get the green for it?

Thanks.

normally, its not recommended, it might not work. But i have used a code before on a DIY site last year and i still received credit but not everyone was successful in getting credit with the code applied.

So you're saying it'll DEFINITELY work...

I understand.

Haha, I kid, but if it has worked before, I'm thinking it just might work again...

Worked for me.

Where do you type in the code?
