Well, they show you how to create the store and cart system, using mysql, xml and asp, but not how to integrate the whole thing with a secure check-out process, i never used their system (coz i don’t know anything about asp), just parts of it to build this: eyezberg.free.fr/download…NLOAD.html
(survey doesn’t work, don’t bother to send it in 
)
I’m currently re-reading the book upuaut mentionned, apparently it builds something similar…
Site workshop is quite expensive, i might be able to provide the source files, if that is legal?!
