I especially liked the price of the Sam's stuff. My big mistake when we started homeschooling was overbuying, especially for the first couple of years. We wasted a lot of money that way.
We used Saxon Math starting at Math 54 and going all the way through Calculus. That's why we chose it, because by not skipping around to different curriculum, we would be pretty sure the kids didn't miss anything.
We used Rod & Staff, the Mennonite publishing company, for phonics and English. By 7th grade the English is pretty rigorous. When I checked out Abeka's high school English, it was the same level as Rod and Staff's 7th.
Rod & Staff also has a reading program I really liked for 1st through 4th grade. The readers were all based on different books of the Bible so the kids ended up with quite and extensive knowledge of the OT and some of the NT, but it was the workbooks that I really liked. The thing about R&S is that the books are pretty inexpensive and they are very basic; easy to read, clear, appropriate sized print, and not filled with lots of distracting inserts and stuff. Color pictures have their place but to much busyness on a page can be distracting. The lack of extraneous stuff, IMO, makes it easier for the kids to focus on just the reading.
After the Sam's stuff for the elementary grades, we ended up with Abeka for science, health, and social studies. I really liked their Health. For S.S. we tried Alpha Omega and my daughter really liked it. She said it presented history from a different perspective. It dealt more with the why of what happened insted of just the facts and dates. That was her opinion and she liked it better.
