There are plenty of places to get free homeschooling materials. Is it true that you get what you pay for? I believe that even though there are free resources available to homeschoolers, most of them are very useful and valueable. Just because something is free doesn't mean it is junk.
No matter what your homeschool budget, it's always fun to find things that are free. It frees up your resources to do fun things like take field trips and vacations.
Don't ever let the fact that you don't have any money keep you from homeschooling. You will just need to trade a little bit more of your time for money. Just because someone watches an expensive video curriculum or completes and expensive workbook, doesn't mean that they understand the the material they have just studied. The amount of money you spend on homeschooling has very little to do with how much your children will learn and retain and how much they will enjoy learning.
