If you have one of the connected HP printers and have been thinking of subscribing to one of their monthly paid ink supply service, you can get the first three months free. Firstly, use my code here, using this link http://try.hpinstantink.com/qflL6 This will give you (and me) one month free. You can then also add the code FREEINK and get an additional 2 months free. That is your first 3 months free Also, unused pages roll over to the following month on the paid plans. I have the monthly plan and it seems to be working well so far for me.
