Switzerland vignettes

[MrsSalvoMontalbano]

Have seen these appear to be able to be purchased from a site cvalled 'tolltickets' - is this ok? Seem to recall someone recently saying that vignettes could not be bought online? Any advice gratefully received...

I've never heard of them. But you can buy the auto vignette at the first petrol station you come to once over the border.
Or, if you're stopped at the border, the border police will sell you one (I assume you're not already in Switzerland .
