Where can one purchase hardback Saxon math books?
Before you begin shopping, please note the importance of having edition numbers, as well as printings, match for ALL parts of the math curriculum you will be using for a certain child; for a certain year. If you buy a book at eBay, then carefully order your supplements to exactly match it. (I recently purchased one teacher book, plus 6 student texts of Saxon 54. I made sure that the editions were the same, but it turned out that I only have 2 student texts with problems and answers that match the teacher book.
