As an Affiliate on CCBIll, I have not worked through the possibilities to receive $_POST data for purchases made by customers on Sponsor sites, who clicked-through from my links with linking codes, on my sites and blogs.

As an Affiliate of other Sponsor sites, including all of the VOD partners and Amazon, I assume that that customer info is held close to their chests.

That's wrong in a way, because I find that those sites are too big and too busy to do customer retention.

All of us who send traffic to Sponsor sites, will lose members and credit for members, over time. Customers love to change e-mail addresses every few months to few years, to reduce spam, and/or to avail themselves of new "free minute deals" for new members!

Over the past 8 years, I have signed up 530 members to one popular Sponsor site. Monday, they gave me a report, that I specifically asked for, showing that I had *seven* remaining/surviving members with cash on hand, or unused free promotion minutes!

Seven members with the same e-mail address and account, that they originally signed up under!

What about the other 520? Besides the percentage who actually died, and a percent of the population do every day, there's 300-400 who changed e-mail address, and are now members of other Affiliates, or of the Sponsor itself.

I assume the latter, because the customer knew the URL of the Sponsor. He changed e-mail, and got new free minutes or whatever promotion of the week.

As an Affiliate, as I do as a Sponsor myself, would send e-mail, and am not above sending letters with stamps, to try to retain a customer.
