Pereskiopsis

Hey guys. Don't want to sound greedy but would anyone happen to have a pereskiopsis cutting spare to give away?
Just interested in the one cutting.
Wanted for grafting ariocarpus to.
Will pay postage of course.
It will be greatly appreciated if anyone has any spare.
And good karma may just come someones way as I may put up some free plants up for grabs in the not so distant future (don't hold me to it though).
