From their announcement:
Due to high sales the initial print run ran out far sooner than we expected but now UM001 is back from the printers and back in stock. Thanks for your patience in the last two weeks. All email orders already placed will be dispatched first, please now feel free to order once more via our website.
Scroll down the USE ME page and click on UM001 to order. Also scroll down further for links to independent reviews of this rule system.
At only £3.50 you can’t get better value in print.
