Disable Product Display upon purchase of the Product or it's variations I have a site of products wherein each Product Display has 2 Variations (Products). 

I would like it so when a single variation is purchased the Product Display get's unpublished (regardless of a variation still being available for purchase). 

I've been trying to do this with Rules with little success, has anyone come across this before or know of a solid solution?
The Disable product when it was purchased issue on d.o. deals exactly with this problem.
