The School Box has lots of educational items including furniture, workbooks, school supplies, and teacher gifts. It is a specialty store but does carry some items you can purchase elsewhere which I would recommend because the prices here are on the high side.
There are many great resources for parents who home school their children. There are also great developmental toys such as manipulatives (beading, lacing, blocks, etc) and teaching puppets.
If you're looking for something educational that you can't find anywhere else, look here.
