*** This deal depends on if you have cleared your browser cookies/cache/history since the first £1 Gold/month deal.***
I always leave a good glitch tab/window open and it looks like it's paid off for once. Check your history for Xbox.com pages from around the time of the original £1 Gold deal.
Try to find this link https://live.xbox.com/en-US/Flows/ManageSubscription/ChooseSubscription.aspx
in your browser history and open it. That's the link I found in my browser that took me back to the original £1 deal.
Login to Xbox.com in a new tab/window.
Click the history link again and it >> "might"<< take you back to the £1 for one months gold deal if you still have the original window/tab open from a couple of days ago or in your history/cache.
So the £1 Gold deal came up again...shock! So clicked next and the payment screen came up.... Then I chose the option to create a paypal account and called it xbox account or whatever you want, then it took me back to the £1 deal screen. Paid for it then I went through my history to call up the link again..... and it gave me the chance to do the deal all over again! Did it so many times (x23) I was starting to get bored but now my account is maxxed out and will finish on 22/05/2014. Cheked my email and got 23 paypal receipts.
Look in your browser history and try it. You never know it might work for you too!
Update* Just woke up and checked email. Have now got the "MS *Xbox Live. MS Purchase Confirmation emails which were received at 02.58am
Update* Got into work this morning and tried to get the link to work again but now being taken to 1month Gold £5.99 so trying to expire now.
