From this week we will be running a weekly Facebook competition where the winner will be given a free 'Essential's' T-shirt. The competition format will change each week just to keep it a little more interesting, so keep your eyes peeled on our Facebook page for the posts. 

This week's challenge is to find a hidden task somewhere on this website or on our Twitter/Facebook/Flickr pages. Complete the task and you could win a t-shirt. Get searching!
