A little exchange with 101CD, hopefully self-explanatory; Do you like 1-click ordering, or is it a bigger security risk than IE and Al Quaeda rolled into one? Is the whole business of having to register as a 'New Customer' or find your log-in details for 'Returning Customer' a pain, you'd sooner just fill in the boxes at Checkout? Do you let sites hang on to your card number? I try not to, I'm also annoyed when I start to enter it and find Firefox autocompletes the number. Why can't I blacklist it along with unwanted cookies? 101CD get top marks for a quick response, but their badly-written system caused the hang-up in the first place to my mind. Or is it paranoid to delete your own credit card details after use? I don't think so.
I think that it's fairly sensible to assume the worst, as most companies are less than secure with personal data. Firebox have a good system, you fill in your details each time, the conformation email contains a unique id which you can then enter on their site with your email addres to track your order.
