JourneyEd is an academic software vendor that carries these products, though they, like most vendors, require proof of academic status. While I was looking over their purchase requirements page, I noticed that they offer their products to homeschoolers, too.
Those who are home schooling must provide a valid photo ID, and a copy of one of the following:
- Letter of intent to home school addressed to local school district for current school year.
- Home School Legal Defense Association membership card.
- Home School Charter School membership card.
- Book/curriculum receipt for the current year.
