However, I can confirm that the apothoke will sell you a 100g jar of bicarbonate de sodium (baking soda) for around 5chf.
Not too surprisingly, four years later and Fenwick's is no longer there.
Try this one:
You can buy Arm and Hammer baking soda, 454g, for 4 CHF online here:
Denner.

Actually, I've taken to getting boxes of Arm & Hammer at REWE. I believe it was €2.50 or there about.
Less helpful to folks without access to REWE, but for those of us with access, I think that comes out cheaper than online.
Hi Tom
could you perhaps post a photo of the packaging of this, from Denner, please? Haven't found it here, and a photo might help to have it ordered. Thanks.
Citric Acid is definately available in the Apotheke's if that helps.
But I would recommend ebay....
I has some sent last week from the UK on ebay.
You can check out in some Indian store . They have it. I think there one store name Aggarwal's there.
