Use voucher code 15HNB as advertised on website and click collect at store to get for this price - can't tell you what it is or what it does, just sure I haven't got enough hair left to ever need one but have been looking for this at a reasonable price as on my wife's christmas list and apparently the next big thing in hairstyling for younger women, always seems to get good reviews and heavily advertised.
Unable to find anywhere in stock for less than £24 delivered (at time of posting) so seems a genuine discount. Also selling out fast (Asda and Sainsburys have both sold out quickly as soon as on offer at around £20 delivered). Good availability nationwide at time of posting. Don't forget Quidco at 3%.
