Click bank sales question for ebooks

  The current ebook I have works like this:
- Anyone can download it for free
- Only the first 3 chapters are visible, they pay to unlock the rest
- The link in the book sends it to one of 20 clickbank referral links (based on the password)
- After payment they are sent to the appropriate password page

(Ok pretty standard so far....)

What I WANT to do is:
- Have them pay BEFORE downloading
- Pay through clickbank
- The difficulty I have is assigning the correct password to them because its not even generated until after the ebook is run

My question: is there anyway to set up a "Pay for the download and then get the right password you require" system using clickbank?

Question #2: If a person downloads 2 different ebooks from me and both ebooks use the same password list of 20 passwords, are the odds only 1 in 20 that they won't have the same password?  In other words does the ebook compilor change the random password assignment between ebooks?  (Hope that made sense!)

The reason I ask is that clickbank only allows 50 links so I figured I could recycle some for multiple uses as long as I charge the same amount

Thanks for any insight!

It's not pretty, and unless you have some kind of script it wouldn't be automatic.

If the only reason for doing this is to recycle product numbers, check the ASP and PHP 1000 password script threads in this forum.  These allow 1000 passwords using just 1 clickbank id.

#2 Yes 1/20 provide your 2 ebooks after different ESBNs

20/20 if they have the same ESBN
