Bread yeast in Basel / Weil am Rhein?

Hi,

anyone knows where to get cheap bread yeast in Basel or Weil am Rhein?

I wouldn't mind getting the fresh type, which is usually cheaper and pretty effective:

But if no one knows where I can get that, I can also do with the dried type that is sometimes found in supermarkets (or so I think, the Lidl I go to doesn't seem to have it).

Thanks in advance.
