Alpha Omega has been producing Christian Home School products since 1977. They publish the Horizons Math, Penmanship, Phonics & Reading, and Spelling & Vocabulary programs as well as Lifepacs and the Monarch software. As of 2024, AOP does not allow discounting of their products except for a 10% discount during the last two weeks of April and a 5% discount during the first two weeks of May. While we'll be happy to honor those sales, you'll have to ask for them!
