I have a brand new CD-Rom for sale.  Rainbow Rock (grades 1 and 2).  I ended up with two of these somehow.  The CD-Rom is brand new with no scratches.  There is no plastic covering it anymore.  I took it off to check it out and make sure it was going to work.  It works great.  Singapore Math sells them for 31.50 plus shipping, and Rainbow Resource sells them for 31.50 plus shipping as well.  I am selling mine for $25.00 with no shipping.  I will sell it first come first serve.
