I was checking instore today (Addlestone) and the men's cashmere jumpers are normally £35 but there were some marked down to £25. I took a v-neck in grey to the till for a price check and it scanned at £17.50. Not the greatest quality of cashmere, but it is 100% and better than other materials, so for this price I consider it worthwhile.
They had lots of them, so I suggest you get it price checked before buying as we all know what Tesco's can be like!!!!!
