From memory, "No purchase necessary" draws are free to enter so do not require licensing in UK.legally how does this stand on the usual 'no purchase necessary' requirement of most competitions?
lawyers? is that something that they must do or just do for a specific reason?
As GW are an international game company, I imagine they have a gaming license for each country anyway to cover all the store opening competitions and other things they run form time to time.
Edit: GW just announced you do not need to buy anything.
