Product: Loads of stuff - GAME console package, Argos vouchers, Asda vouchers, Littlewoods package
In order to enter this competition you need to be NUS-registered and have a Facebook account - obviously it's completely free.
The way it works is that you select which prizes you'd like to win from a big list (I chose GAME console package, Argos vouchers and Littlewoods package).
The prizes are then given at random IF your Students Union enters the most entries.
Bit of a weird competition but free nonetheless, but still, you apparently get a free CDWOW voucher for just entering. I'll update this thread of how much it is - not expecting more than 50p to be honest.
