Every year there will be a mention in the local press of British tourists who had hoped to get a real bargain on a chalet in Verbier or Zermatt sending off large deposits or even full payments for nonexistent properties. Then they show up, in the middle of peak season, blaming the locals for their problems.
If it looks to good to be true, it is!
Funny, I've never seen reports of tourists from other countries ... but there must be, surely.
