Is white vinegar, bicarb of soda etc REALLY cheaper for cleaning?? Where can you get it in bulk?

I like using vinegar and plain bicarb of soda for cleaning, but have only been able to find them at the supermarket in smallish packs and bottles.

By the time you've sloshed the white vinegar round the bath it seems half the bottle is gone, and at about 60p a bottle it doesn't work out that cheap.

Also the supermarket packs of bicarb of soda are quite tiny, so not really any cheaper than normal cleaning scrubs, in fact maybe even more expensive.

Am I doing something wrong? Can you buy big 4 litre cartons of the stuff somewhere?

The plasticky net bags you get citrus fruit in is a really good scrubby for getting gunk off baths, ovens etc...
