I'm sure this is the message board equivalent of forgetting your wallet in the pub, but I'm having trouble following the link to the bit where you pay. The site has been stuck in mobile mode for me for a while, regardless of what device I'm on, and that seems to be the issue as the link on p.1 just opens a new general H&V tab. Help!
Edit - don't worry managed to find it by logging out so that the site reverted to desktop mode and the payment button appeared. Cheers, keep up the good work!
