WKD, the no 1 ready-to-drink brand, is celebrating its sales success by giving readers the chance to toast Hallowe'en in style.

The brand is going from strength to strength in the take-home market with strong volume gains this year.

It is now a decade since WKD was launched into the UK market with its Iron Brew variant. In that time it has seen a number of rival brands come and go. It has also launched other variants such as WKD Blue, Silver and Red. With sales up 16% to £55.4m year-on-year, WKD this year became the bestselling RTD brand [ACNielsen MAT to 12 August 2006].

It is known for its wacky TV ads, with the strapline 'Have you got a WKD side?'

The brand is offering ten lucky readers a free case of WKD Original Vodka Iron Brew - which is the perfect accompaniment for a WKD Hallowe'en.
