Website glitch means you can get the card for £5.99 instead of £11
Click on NUS Extra
Sign up for a card
When you get to the payment screen, close the tab/page
Re-open the website and log in with the details you used on the sign up page
Click on 'my account'
Order a replacement card. Comes to £5.99
Even though you didn't buy the other card, it still works and accepts paymentna dn I have received a confirmation e-mail.
**Unsure if they are actually going to post these out but worth a try for students.
