Question about Red Band Acid Tongues

I'm confused, something can't be right: a 200 g bag costs 17.90 francs? I don't know what exactly it costs in the Coop, but it's probably somewhere between three and four francs (for original Red Band "Sour Tongues"). Is it perhaps more than just one bag or why should 200 g cost almost 18 Fr. - especially as a tub of 1200 g only costs just two francs more...
