The FollowupPurchase concept makes use of the DistributedPzn framework to increase sales of products we offer online.

For instance, consider FoodTV's shopping site.  If a person were to purchase the red Iron Chef t-shirt, we might like to target them to purchase the black Iron Chef polo shirt.

To accomplish this, the sales confirmation page makes a call to the distributed personalization FollowupSalesAgent's PznSetFacility, indicating that this person might like to buy the polo.  This action is transparent, and requires only a single line of html to be added to the confirmation page.

Now, the sales agent's PznRenderFacility will display an ad for the polo shirt with a link to the checkout page for that object.	That object may set a new followup sales target for the user.  And so on, and so on, and ...


'''Consider this scenario''':  the PznRenderFacility for FoodTV sales is used on the InsideDenver Life Style section page.  The page contains local content mixed with some FoodTV content.  Normally, the rendering agent just links to FoodTV's commerce site.  But once the user has clicked through to foodtv.com and purchased something, the followup purchase is promoted not only on FoodTv.com but also back on the Rocky Mountain New's web site.  If fact the system is so non intrusive that we could get the Denver Post to use it with no modification of their systems.  Essentially any site can become a promotional tool for our wares.
