This Creativity for Kids Glow and Grow Terrarium Kit drops from $24.83 to $9.99 at Amazon. This is the lowest price you can get compared to any similar terrarium kit for kids. It includes glow-in-the-dark sand, stickers, and forest figurines. Prime members get free shipping. Non-members get free shipping at $35, otherwise it adds $5.99. Editor's Note: I highly recommend this toy! It started growing in only two days.
