I wont be going back there then if they are profiteering in the middle of a crisis i will go somewhere where i can get them for cost price.

I'm in the building trade and sell quite a lot of stone. Usually from demolished walls, outhouses or yards. I get between £20-25 per square meter, depending on the individual size and quality. Thicker ones are worth more but I've never come across 8" thick ones! The price will depend upon whether they are delivered or collected. HTH

you'd need bloody big flagpoles for 8" thick stone flags wouldn't you?

Not on the moon, where the Yorkshire flag was in fact raised before the US flag
