I can second that - I bought one from Sainsbury's a couple of months ago, last time they did the 25% off. Huge cosy fur trimmed hood, long on the bum, very warm but not too heavy. Only downside is that my DD says it is mud-coloured
I got a lovely warm one in Matalan for £35. It has a nice soft thick lining. I got it about 2 months ago and I can't see it on the website but worth going to have a look to see if they still have them in store.
