My product is a very expensive seminar to a certain set of industry professionals who have already taken a course with us.

So when they click on a link in this email, it is listing a calendar of events, in their local area, and they almost always will choose just one. But when they do choose it, the 1st screen they see is the screen we would present as if they just added it to a cart on our site. Then they can "shop some more" or go to checkout.

The checkout screen has the various information we want to avoid having them type.
