I am sending something to an eBay customer I sold something to, they arrange collection through this service. They emailed me asking to confirm the collection address. I cannot confirm the collection address without signing up, I can't just respond via email. So, I have to sign up annoying but fine. However, I can't sign up unless I want to send something. So, I have to fill in a lot of fake information about a product that doesn't exist to get signed up to respond to what should have been a simple click of a yes button to confirm. Why not just have a button on the email that says confirm?
