Hi, Not sure which lancets you have, My first meter came with a multiclix lancet, however I think the new meters now come with the fastclix lancet. The lancet drums are not interchangeable. You should be able to get them from your local chemist or online from any number of places.
I'd try my Gp first, even if you don't get test strips, you might be able to get a box of lancets, whichever one you have, the box of cartridges will probably last you years.
