Hi @STANDSU,
Sorry to hear about this confusing experience. It’s possible the email automatically triggered in error - or occasionally, stock of a particular spare part is limited and sells out quickly as other customers who have signed up to be notified click through and purchase.
Best thing to do is to live chat with our Experts, as they’ll be able to double-check availability for you - and if the power cord is available, they should be able to process your order.
Please head to Dyson.co.uk - once you’ve opened the Dyson Digital Assistant you’ll be able to click the agent icon in the bottom left of the chat window to start a Live Chat session with one of our Experts.
We’ll look forwards to speaking with you!
