Am happy to receive the CD from HaveFunTeaching.com all the way from the United States. It is one sample from facebook. Nowadays facebook is a popular source to advertise your products and gain popularity. The CD is valued at US$12 so that means it costs S$24. It is an educational CD that covers the various Science topics such as matter, planets, senses, water cycle, seasons, animal and so on. Hope to get more samples through Facebook.
