The minor inconvenience of re-entering my shipping data every time clearly outweighs the possibility that some crime syndicate gets their hands on my personal data. At least for me. I would appreciate it to at least have the option to not create an account when I make a purchase. I've seen too many data breaches to have much confidence in the security of the majority of webshops. The only secure safeguard against theft of personal information is to not have it stored in the first place.
