Kiss of fortune refill/alternative?

Hey babes, at the start of this year I purchased myself the "matte revolution kiss of fortune lipstick" by Charlotte Tilbury and it is the red of my dreams. I am not nearly done with it yet however, I know that one day I will finish it and I would want to get more. This is my signature lip colour now and I love it A LOT. The shade is "limited edition" according to the website but I honestly hope that this is just a marketing trick so that I can buy a refill when I run out (just under a diffrent shade name).. pls help?
