I spotted this project from Koichi Nakamura
A mother board approach to a Pi Zero cluster
Yes Andy stick 30++ PI Zeros which are either unobtainium or £30 ea from Cool components then stick them in an expensive carrier board then you too can have a cluster with the same compute power of an 5 year old Atom CPU 
Nice toy but Clusters of RPIs are a joke and merely noise to stop us looking at any number of much better boards out there!
Looks like cool components have tried to do something to improve their position on the price elasticity curve, they have "slashed" 
prices heavily down to a mere £24 including tax. Their stock has now depleted from 6 to 2 in 48 hours. : ) Hardly popular item at these prices.
They're out of stock now.. price now set back to £6, so no-one is the wiser : )
The twitter response from a week ago,.. interesting how they treated potential customers I thought..
I don't entirely understand what they mean by "no proper reseller program" 
That's why I delayed some purchases, waited for Zero to be in stock and combined the orders 
The Pi Hut had them at £4 + £2.5 shipping.
