It appears the glitch to sunseed trading that resulted in customs holding up shipment and prices going south as a result was indeed down to an over zealous Yuri or to be charitable a bottle neck at the port.Prices have started to return to normal with latest quotes back to what they were previously i.e. north of 4,000UAH (308GBP).
Phew, we can breath again, at least until the rumour mill starts up again.
