Homeschooling does not need to be really expensive, but it is wise to do some financial planning for your curriculum and other resources.
Following are some tips to homeschool on a budget:
Websites for Used Curriculum:
If you are a member of HSLDA, you may use your membership card as a "Teacher ID" card, and receive discounts at teaching supply and office supply stores.
Attend homeschool used book fairs & curriculum sales; you can get some great bargains, and some people even donate free books. Also watch for library sales.
