Neat 100 litre water buts at Argos

[BDG]

I am in the North East. As I said, look in your local ad paper if you have one. You can pick them up on Ebay too, get them delivered on a pallet but pallet delivery is normally £50, but you may live close to one of the sellers. You might also find it easy to contact someone at the local allotment association, they should have contacts local to you for them.
