Plus p&p works out at under £20 from tesco direct. If you are spending over £50 anyway its free delivery.

The Remington Wet 2 Straight S700 straightener has anodised ceramic plates for even heat performance. Special vents allow water to evaporate quickly when straightening wet hair, while still retaining its moisture. It has a 60-secs quick heat up and 130° - 200° C variable temperature. This Remington straightener is complete with 3m salon-length cable and plate lock switch.

These work very well (I had a pair of these myself a couple of years ago when they were selling for £80 a pair)
