Copying from the teacher’s guide or student workbook is not permitted. The only copies permitted are from the assessment unit. Whenever you would like to return manuals, please email or call us first. We are always able to custom design a program for you. If you would still like to return the curriculum, manuals need to be returned within 7 days of receipt. They must be in brand new condition. Assessment units must not have the shrink wrap removed. Your money will be refunded to the original payment method, minus shipping and handling. Orders $500 and greater are final sale.
