First off, a competition on the Original Source website – submit a photo or video which “best demonstrates the spirit and values of Original Source in the most appropriate and unique manner”. Good news too – this one will be judged! The promotion closes on 21st October and the prize is an 8 day Yucatan Adventure tour.

Next, on the XFM website you can win a trip to Mexico for you and three friends in conjunction with Jose Cuervo tequila. Just complete the online entry form telling them about “a legendary night you have enjoyed with your mates” in 100 words or less. This one closes on 17th December, but don’t spend too long on your entry as it says the winner will be randomly selected.
