I took advantage of the lousy weather and went and bought some more 25 litre containers. My Mrs can now fill the next days supply while I'm out working.
Saves me a lot of time in the evenings.

£1 each for cash. They also do 800 and 1000 litre caged tanks.
They will deliver, and it works out about £17 for 10 containers.
