Hello, does anybody know a bank where I can open and manage a Rental Deposit Account that does not cost 100 CHF? 

I only need it for 6 months, and I find 100 CHF a bit steep for a service I use that shortly... It seems many banks are sneaky about the fees also, advertise no fees but then you have to pay 50 CHF or so for the actual deposit or similar. 

Looking for the cheapest option out there. 

Any help is appreciated :)
