Can I replace a few books inside a Package?
When you purchase a complete Core package you are eligible for a Club discount on everything in your order. No substitutions or deletions are possible.
Sonlight chose to offer this discount because the purchase of a complete core speeds up the shipping and handling process. It is much simpler for those in the warehouse to grab a complete package off the shelf for you. (It is simpler for you to order a complete package also - no typing in individual item numbers! And, don't forget the full 18-week guarantee when you purchase a complete Core!)
When comparing the individual price of the books they already own with the value of the discount they receive on a Core program and any additional items ordered, many clients find it actually saves money to order the package and duplicate some of the books! Those families will often use the duplicate books for gifts.
