I own teacher and homeschool supply store. I need to find early childhood, elementary, middle school,?

and high school textbooks. I try the major companies, like prentice hall, harcourt, etc. but they only sell to schools, parents. etc and they only will sell at their cost. Half.com, amazon.com, ebay.com sell textbooks but not a large quantity. I don't need new editions, old editions would work fine, is there book wholesaler i can buy these from.

I'm not positive but try Baker %26amp; Taylor and World Almanac, they might do texts.
