A trip to London stadium is currently reduced to £10.20 on the website.
First time users get a £10 off voucher by email.
When booking the tour, use the £10 off voucher and the tour is then 20p!
The voucher is valid for 20 months and currently can be renewed/changed at no cost until it is safe to go there.
No guarantee the company will still be going when everything is back to normal but for 20p, it's worth the chance.
There is a warning that if people are found signing up for multiple accounts, they risk having ALL their accounts terminated and thus losing any accumulated vouchers.
