You can do this within days of your gold about to expire to extend it for about a month. Tutorial: Wait until your gold is about to expire. Visit this link. Change your region to UK or US, depending on where you live. This will now extend your gold membership by a month (usually a month) Draw backs: This will swap your currency to whatever region you changed it to. You will get that region's ads. You can't change your region back for 6 months. Some of these draw backs can be a pain in the butt, but are nothing too gameplay impacting, especially if you can't afford your next subscription of gold!
I contacted xbox about this trick, and they stated that you can actually get banned for changing your region so many times over and and over. just be careful, i do not recommend this to anyone. Best way to extend your live is to ask around if anyone got any trial card codes, i had one for 14 days once and 7 days trials.
Just forewarning, changing your region a lot is highly noticeable, there's systems in place for acts such as this, such as if you change it more than 4 times or so, your account could be flagged for investigation. so if you do this every 6 months, take that with the knowledge that you could be hit with a large drawback such as being banned for a short amount of time, or more time if it is not your first offence.
