Are you an organiser for a Usergroup be that Linux/Windows or some programming language ?
If so then you could be like us an take benefit from O'Reilly's User Group scheme!
I applied through their online portal here and a few weeks later a swag bag of general "stuff " appeared.
I even got a pencil ....Propper CrackerJack!!!
More importantly you get a discount code for your group to use when ordering (Suitably deep !!) as well as a monthly newsletter detailing new books and promotions.
Simply put you get the chance to get the lattest stuff, a discount and .... sign up here!
Update User group Members can ask the group leader to apply to join as it's all co-ordinated via usergroup leaders!!
