You've booked and paid for a ticket via the book online section of our website.
This sends an email ticket to your email, but you haven't received the email.
You've checked your bank / card statement and you've definitely been charged / paid.
First, check (and re-check) your junk/spam folder as in 99% of cases that will be where the ticket is.
If you can't find it there, please don't worry! In our computer in reception our volunteers have a list of everyone who has booked, their names, their ticket code, and how many people are on the booking. So please just give your name and the number of people in your booking and they'll check your ticket there and allow you entry to the museum.
We look forward to welcoming you to Derby Computer Museum!
