Re: Fake PII FTW.
You *need* nothing from me beyond a method of payment and an address
A lot of the better vendors allow checkout as guest where the only thing required is an email address and the payment is handled by their payment processor. Since I run my own email server (and no - it's *not* MS Exchange) I generally use $firstname-$sitename@mydomain.blah.blah as the email. That way, if I start getting spam to that address I can dob them in to the Info Commissioner on GDPR violations..
