I'll be watching your topic! One way that we have cut back alot is on my prescriptions. We use an online pharmacy through our insurance. I also consolidated our cell phones (we each had a different provider).
The only other thing that I would say is don't go too crazy cutting. I think the key to making an austerity budget work is cutting enough that there is real savings but not so much that everyone feels deprived. Draconian cuts can rarely be sustained for long periods of time.
Do you really want to go without internet service? For example, if you're homeschooling wouldn't the internet be a useful tool - not just for the schoolwork but for curriculum?
I am looking forward to other's responses.
