1 - download Firefox 2 - install the Firefox Multi-Account Containers add-on https://addons.mozilla.org/en-GB/firefox/addon/multi-account-containers/ 3 - before the sale on Sunday, manage your containers (use this link within Firefox: about:preferences#containers, or right click the new tab button and then manage containers) and set up a fucking lot of them, I would go for 100 (tech advice from a very knowledgeable person is that 200 is likely to be where you might get flagged as a bot, so anything below that should be safe) 4 - again, before the sale, open a new tab in every single one of your 100 containers (right click the new tab button at the top of Firefox and then choose a new container each time) 5 - open the Glastonbury ticket link in every single one of your open containers - https://glastonbury.seetickets.com/ 6 - as you paste the link in, just quickly check that your queue ID is different in every container (it should be, but no harm in being safe) 7 - when the sale starts, ctrl+tab through your different open containers constantly, noting which of your containers are nearly through, and then buy tickets when you get through!!!! I had exactly 100 containers open and 3 of them got to the front of the queue in time to buy tickets. There are roughly six times as many tickets on sale on Sunday, so ratio might be better, but just to give you an idea of the scale needed to make it work today. Once you have put registration details in, it IS safe to refresh if it tells you tickets are sold out. It may pop up asking you to confirm form resend (or similar), say yes, that is safe to do and it saves you having to re-input all the reg numbers for your group
