Doris, to your most recent question, after there were some accounts removed a couple weeks ago for advertising, the moderator clarified the policy on publishers, saying that they are welcome on the board to address specific product questions. I decided that would be a good opportunity to address the occasional question that comes up on the board.
Saxon has customer service reps in Orlando, but our primary office staff is in Austin, TX.
Lisa, Math 7/6 and Algebra 1/2 were both created before Math 8/7, and Math 8/7 was originally created out of a desire to bridge the gap between the two books. In its first edition, Math 8/7 was considered to be not much of a step up from Math 7/6, so many people skipped it and went straight on to Algebra 1/2. So Math 8/7 was strengthened, and the second and third editions much more closely resemble Algebra 1/2. This is why there are two books. The main difference is that Math 8/7 is formatted like our middle grades books, with Investigations and daily warm-up activities, while Algebra 1/2 looks more like our Algebra 1 book with more introductory content. There are people who prefer either book for various reasons--they both provide preparation for Algebra 1 and will both continue to be available.
Doris, I hope this helps. It is not our intention to advertise, and we don't have any opinions on what stays and what gets deleted. (I thought the advice was helpful, and I'm assuming the deletion was because of previous activity.) If you have questions that come up about the Saxon program, you can always send them to info@saxonhomeschool.com.
