Homeschool Buyers' Co-Op (a place where you can buy new homeschool curriculum at discounts through group buys) is offering a Summer membership to VocabularySpellingCity +200 SmartPoitns with your purchase of a subscription to Time4Learning. Offer is only valid for brand-new Time4Learning members.
We have used Time4Learning this year, and have enjoyed it. I plan to use it again next year, especially when I take a few weeks' break from homeschool with the birth of the new baby in November! It's not free or super-cheap, but worth the money we spent on our membership (you CAN get it cheaper, and one way is through Homeschool Buyers' Co-Op!)
