just had an e-mail today from The Snowcoach Team [info@snowcoach.co.uk], which is the arm of Cantabrica that does their winter holidays.
same address/phone number etc.
they are taking bookings for winter ski holidays.......

the cantabrica website shows 2011 prices, with no indication they have ceased trading.
so it looks like part of their business is still going and so, at the moment, summer sales for 2012 are possibly being taken by phone as you can still e-mail them for a quote.

i would be very wary.....................
