Hope it's not down until December 6th!!
Here's what the website says
We're very sorry...
Due to exceptionally high visitor numbers on the site at this time, some customers are experiencing difficulty accessing the Clubcard website. Please try again later.
To exchange in-store*
If you wish to exchange your vouchers in store to spend in-store, take your Clubcard vouchers to the Clubcard desks at your local store**, where a customer service assistant will exchange them for rewards tokens. Make sure you request either an in-store or an online/ Tesco direct rewards token, which will look like a till receipt (Check in-store for full details)
We apologise for any inconvenience caused and look forward to seeing you soon.
