Happy New Year! Time to think about buying curriculum?

Now may be the time to start thinking about next year's curriculum. If you are quite certain of a particular curriculum that you will indeed be using next September, and you are in a position where you MUST be a bargain hunter....now is the time to find great deals on used books. Often we wait until peak time to look for those used treasures only to end-up in a bidding war.
However, in contrast to what I'm saying, I must applaud www.christianbook.com for offering such a great discount on Apologia last August.
However, here are some sites where you may be able to find a great deal on used curriculum:

• http://market.hslda.org/auction/xcAuction.asp
• http://www.paperbackswap.com
• http://www.half.com
• Various sites managed by homeschooling families

Please feel free to list a site in the comments section to this post.

Happy New Year!
