Best website to buy SWISS VIGNETTE - or - Got one For Sale?

[Philiptigerrice]

So - we're away to the Black Forest soon - and will probably want to bimble into Switz for a bit - (family car trip) - can anyone recommend a reputable (and not rip off) vignette website - I'd rather buy before I go.

Or - does anyone have one for sale

I understand it's naughty.... anyone any advice on that too?

Avoid motorways and don't buy one. If you need one, they sell them at most petrol stations, in the surrounding areas, around Switzerland etc
Been through Switzerland three or four times, planned my route a d didn't get one. As in an emergency they are readily a available locally.
