There was an overall sale in European flights
Yesterday. I was linked to Travelmerry as the cheapest offer online. I try to book, and at 4 am the night after I recieve an email saying they can't process my transaction. I try again and again and again. Call them and they say keep trying. Then I email them and they inform me the airline can't confirm the tickets, please book directly with them". By then the Europe sale was gone at every legitimate travel site. And they still have the wrong price listed.
