Brother just called to say he had picked up 8 bags of this stuff from his local Homebase @ 43p each. Was going to buy 4 bags anyhow but when he got to the counter it went through at 43p a bag so he grabbed another 4.
Not sure which Homebase store it was but he lives in Bournemouth, not sure how many in the area.
Checking out my local tomorrow as I have 2 sheds going up next week, would normally mix my own but at this price.
They were 25kg bags
