Here's what I'm after, I'll try and make it as clear as possible.
1. User buys a CB product on my site, with the promise of a free gift. They're given instructions to submit their tranaction ID into a form and send it off to me for verification.
2. If they enter the wrong code, or are trying a bogus code, they get a try again screen.
3. If they enter the right code, they get thank you screen.
How do I do this?
Is there anyway to have the form check my CB account for verification? Or do I manually input the transaction ID's somewhere?
4. I'd like to wait a period of time before they get their free gift, don't want people just asking for refunds.
Where should I start, if I want to get the ball rolling on this?
