Bicarb - where to buy?

[CeliaFate]

I can only find tiny pots in the baking section of supermarkets. Where can I buy a big box of it for cleaning?

are you looking for soda crystals?
they are in 1kg sacks either with the stain remover stuff or the dishwashing stuff in the supermarket. very often on be bottom shelf a little bit hidden.

You can buy a bigger tub of bicarb at the pharmacy for heartburn, some places need to order it in though.

costco sell it in big big bags. Arm and Hammer stuff.

I had lots of suggestions on a thread here but our Sainsbury's and Wilkos don't seem to sell it so I need to investigate some of the other options.

summernaturals is the cheapest online place I have found, but the postage means you should probably bulk buy.

Carbolic Soap Co. probably sell it too.

Boots sell it in 1kg boxes.
