I work with a small publishing firm. The head guy (who doesn't quite think things through all the time) wants to mimic Amazon's One Click Ordering on his web site to sell books. First off, it would be a pain in the butt to actually implement because we would have to modify the shopping cart system (zen cart) as I don't think that it has been implemented yet.

But I was wondering what sort of usability questions this raises (not to mention legal issues of storing credit card information on a not-so-secure server). I went to amazon and tried it out. Sure enough I went directly from a details page about a DVD straight to a page that said the order was to be shipped soon. All in one click. There was no confirmation involved, which I would think you'd want for online purchases.

I then had to look around to see what I needed to do to cancel the order

Any thoughts? It doesn't seem so great for the casual clickers out there.
