Just Giving is the simple way to donate direct to the GSG, the good thing is it is so simple to use and they even claim Gift Aid for us, which means for every £1 donated by yourself an extra 25p is paid by the Government as long as you area UK taxpayer.
If you are thinking of doing your own sponsored event, whether it is a sponsored walk, abseil or parachute jump then this is the place to head to set your own page up.
Think of it like an on-line sponsorship form but without having to chase around collecting money after the event !!!
