Buy some white vinegar in 1 liter glass bottles and use the vinegar 1:3 with water to rinse your fruits and veggies -- stay healthy. Rinse the bottle very well, then use to store fixer or whatever. Yes, the bottle is usually clear, but I prefer to keep my bottles in a space like in the cabinet under my sink, where it's dark anyway.
Alternatively, buy a bottle of Irish Cream, drink it slowly, then rinse the bottle and use it for developer etc. These are heavy, extremely dark glass bottles -- ain't no light getting in there.
No, buy a bottle of Irish Whisky, drink it quickly and you won't care about storing your chemicals.
