How can I print out USA postage stamps online using a credit card with a non-US address?

After much research, the answer appears to be that you can’t. To quote http://stamps.com, “The USPS requires you to register your name, telephone number and physical address from which your postage will be printed”. It appears you can only print stamps for mail that is to be sent from your specific registered address, so you can’t use it to prepare stamped-self-addressed-envelopes anyway.
