Until April 6th UK customers can get 20% off Lulu orders by using code EASTER at the checkout. This means there's never been a better time to get
a pre-printed copy of Sudoku Xtra magazine.
This code might well work in other countries, but I don't know - you can sign up on the Lulu site to get their occasional marketing emails (creating an account suffices, although perhaps there's an even easier way!).
