Good Riddance Teespring, Hello Fourthwall

The post recounts a failed attempt to run a Have I Been Pwned merch store via [Teespring](), citing technical failures (e.g., a broken canonical URL and admin access issues), severe shipping delays, and unresponsive support that culminated in an Amex dispute; the merch operation has since moved to [Fourthwall](), where orders were fulfilled promptly, and is now available at [merch.haveibeenpwned.com]().
