So the competition to win a Grip'n'Sip cup has come to an end!
I have used random.org to select the 3 winners (screen-shots below)
The 3 winners are:
Comment number 19 - Michelle U
Comment number 4 - @zanacel
Comment number 24 - Laura Copley
If the winners could please contact me with their name and address I can send the cups out and hopefully they will get to you before Christmas!
