In the UK you can get a years supply for £1912. You sign up for a year pay monthly and automatically receive the sensors and transmitters as needed. Of course with xdrip+ and Spike you can stretch the sensors and transmitters to go for longer and Barbara who puts new batteries into old G5 transmitters says that although it is more difficult she should be able to do G6 when the time comes… Apparently 15 days are achievable for the sensors although as it is so new I have not heard of anyone who has reported the 20 or 28 days some reported with the G5.
If you want to stay with the Dexcom apps Kate Di Simone has provided instructions about how to get longer out of both sensor and transmitter. One way involves using your microwave as a Faraday Cage.

The view from another planet is interesting however the overwhelming reason for getting CGM was to avoid my wife having to call out the paramedics when I went hypo at 2 am. The alarms were paramount.
I have been asked to trial the new Medtrum A6 and am 10 days in. Several times a day I am recording BG using the Contour Next, the Medtrum A6, the Libre/MiaoMiao/xdrip+/ andof course the Libre itself. I have never tried to check the accuracy of sensors in this way before but it throws up some interesting points.
My view is I want at least 20% accuracy when BG falls to 5. That is when meter reads 5 BG reads between 5 and 6 mmoll/L.
So far every system has had at least one reading over 25% out but not in a way to put me in danger of hypo. That would be a reading 5 with BG 3.75 or below. In fact no reading at all has put me in danger of a hypo.
The xdrip combo has recorded 8 out of 10 readings below the BG reading something that gives me reassurance.
Confirmation is building that the Libre sensors are fairly consistent. The first one consistently high over 2mmoll/l at higher levels and the second one, so far, really accurate generally plus or minus 6.
In other words we are still waiting for a consistent sensor that does not wobble around (I have read good reports of the G6) and genuinely does not need calibrating.
I will be posting everything I have done so far on my website after the first 14 days or so. Medtum is supposed to be able to do 14 days.
There was one totally bizarre reading BG 8,2 (taken twice) xdrip and Medtrum both 6.5, Libre 5.6. Totally out of the blue and previous and following readings all within 10% for all 3 systems. Gives ammunition for any doubters but at least it was the right way fronm a safety point of view.
