There is currently a 40% discount at KurokiGoIshiTen to celebrate their centenary - it looks like its for selected complete sets with their blue clamshell stones.

Best Wishes - John

The large discount was just too good for me to pass up. I grabbed the size 41 stone, floor goban combo a few days ago. Will post pictures when the set arrives

And... it's over. I also couldn't resist and bought a board and stones from the anniversary sale. But it's still on its way to me by ship. I figured I can wait for them to slooooowly make their way to me - I've already waited for 13 years before getting this anyway, a month or even 2 of waiting is nothing in comparison.
