We only get 400 strips per 3 months covered in the Netherlands when you're on MDI. Anything else, I have to pay for myself. That's an additional 85 euros out of pocket for me every 3 months so I can test 6-7 times a day instead of 4 times a day. This doesn't include any additional exercise/driving/hypo tests, or malfunctioning strips. For my meter it's €23 per 50 strips and €8 per 100 lancets.
There's no real way to save money for me. I am on the road 4-5 times a week, either by bike or borrowing my parents' car, so I HAVE to test often whether I can afford it or not.
