Cut-rate Curriculum

It's that time of the homeschooling year again, time for doubting your sanity, waiting for test scores, doubting your kids' sanity :), and looking for curriculum at a good price to do it all over again next year!! A few of my favorites for low cost stuff are:

• Rainbow Resource - huge assortment of new curriulum and supporting material - www.rainbowresource.com
• VegSource - a community of homeschoolers connect as part of this website, and there is a ebay type place to sell and buy curriculum (also some really good discussion boards) - http://www.vegsource.com/homeschool/
• Home School Legal Defense Association's Curriculum Market - anyone can sell curriculum here and HSLDA members can buy or sell here - http://market.hslda.org/auction/xcAuction.asp

Let me know if you come arross any other good ones!!
