You can see their CSS here:

It appears to have been a generic ColdFusion template (done in Macromedia DreamWeaver I suspect) just with a few mods done. Of course the server must support CFM files.

If you don't have CFM support then I suspect you could mod any one of a number of scripts easily enough? See OS Commerce for one with a lot of add-ins IIRC. CubeCart maybe - I've played with that a few times - if you wanted to dig into it. You'd have to pay to use it though. Zen Cart is free (and there's a million more free out there if you look) and also fairly easy to mod. They would *like* a donation though.
