No, only roads that are designated, these are indicated with green signs just like blue is used for motorways in UK. Alternative routes are always available.
There is only 1 price.. 40chf per sticker, doesnt matter if its for a bike , car or trailer they all need one. It's valid thru to 1st feb the following year.
Depending on exchange rates used no, 40chf is 26gbp at moment.
Have no fear buying at the borders, if the guy wants to put it on for you just tell him no and put it on where you wish.
Remember not having it displayed even if its in your wallet is the same as not having one. It's a 200chf fine plus the cost of a vignette so 240chf.
I have 1 on the car but dont bother for the bike.
Hint: stick it onto your clothes a few times before attaching, easier to remove as it leaves a nice glue gunk behind.
