I has a similar problem when Kate was first diagnosed. Like Northerner said go to your DSN, mine sorted it out for me. I even looked into buying them myself at the time because we were only just coping with the new diagnosis and I really didn't need any more stress! I had quite a shock when I realised the cost though!!
It seems that every day is a constant battle and like you I really could do without the extra stress! I have to admit to sending a rather sarcastic email back to the doctors asking if they could advise me how to make the test strips last longer! I almost suggested that maybe a quick wash would make them reusable?!?!?!
