Just thought some might be interested to know that although it might not be held in stock, J Arthur Bowers Hydroleca in 25 litre bags can be had from B&Q warehouses for 4.98 per bag...you might have to order it from the service desk, as i did, due to the fact that not all stores are ranged for it....Barcode is 5010672361045, should come in pretty quickly as it's a central depot line....haven't seen it cheaper than this on the web and it's certainly more economical than buying it in the grossly overpriced 5 litre bags at 2.98.

well spotted!

wish a had the cash
