Swissvoucher on Ebay?

Just wondering if anyone has ever bought one of these vouchers on ebay. I am going to Paris next month for 3 nights & could make hugh savings if I was to bid & get one of these vouchers. However, can't afford to waste money either if they turn out to be something odd with these vouchers. Would appreciate if anyone has any experience of these if they could post & let me know. Thanks

93.4% positive feedback is below my usual 'threshold', but... ([broken link removed]'s someone got a week in a 4-star hotel in Agadir for €133! )

I presume you've checked out their own [broken link removed]? (T&Cs at the bottom of the page)
