UK people - what do you store your chemicals in?

For developer and E6 I use the brown concertina bottles (1 litre) currently sold under the AP and Kaiser names.....mine were branded Jessops back when Jessops was a large chain but appear to be the exact same bottle sold as AP today. They seem quite widely available.

For fixer, I am lucky enough to work in school laboratories and I have acquired a bottle which used to hold 2.5 litres of concentrated sulphuric acid....washed chemically clean of course.

I use Gordon's gin bottles (dark green) or coloured wine bottles and Vacuvin stoppers. If you don't drink, I'm sure your local pub would let you have some. At mine they are smashed up and sent for recycling otherwise.
