Golf Monthly: Ryder Cup DVDs and golf clubs.
Today's Golfer: three different trips (Bulgaria, Northern Ireland, Spain) and golf clubs. This is also the same for Golf World magazine, its sister publication.
Golf International Magazine: nothing at the moment... oddly.
Sorry to sat that some prizes are for 'UK residents only', so you'll need to consider that, or give the address of a friend/relative in the UK.
You should also visit different golf club websites as they often have free fourball giveaways every month, e.g. Headfort and Dromoland Castle.
And remember, a golf prize is for life, not just for Christmas.
