Those things ARE expensive! Someone stole mine a couple years ago, and I had to buy another one, so it was twice as expensive for me! It's worth the money though, because I went through all my high school years using one, and it really helps in college if taking lots of math and chemistry courses.
Anyway, I think I saw one selling for around $80 at Staples when it was Back to School shopping time, but I don't know if that offer is still available. |
