No, but Riverdeep had given me the exact same pricing when I contacted them directly. The only difference seems to be the 40% off the second course, which would help you. They also have Destination Reading, which I have not looked into.

The homeschoolbuyersco-op site seems to update things every week or so, so check back. Or join - it doesn't cost anything and they email with updates. We'll be doing CyberEd science through them, too (another huge savings - $32/year vs. $640/3 mos.).
