There have been a lot of rumors flying, together with panicked responses. (Goodwill and Salvation Army won’t be able to sell used children’s clothes and toys! Selling used curriculum will be illegal! etc.)
Here is a link that will take you to a thoughtful analysis of what this act, due to go into force in a few weeks, will mean for homeschool families. I happen to know the homeschool mom and editor who publishes this online magazine. She researched carefully before putting this information online, together with links to more information.
Hope this helps to calm the jitters just a little.
