If it's any help I think this link will take you straight to the web page where you'll need to register a new ticket account:
https://www.eticketing.co.uk/wrexham...tication/Login
You'll need to use your email account to register, then activate your account on receipt of the confirmatory email before you can go ahead and buy tickets. The key thing to look out for is the circular icon next to the basket - that will bring up your membership details (including your number).
This ticket account/membership is then totally separate from any other club memberships.
Hope that helps!
