I just stumbled upon these and thought the prices were great and the educational value is fantastic!
The Mini Social has National Geographic World and USA maps and murals on sale through today at up to 60% off. They are beautiful maps in various sizes. They have beginners maps for K-3rd grade and maps for older kids all the way through adult. They start as low as $8 and have a range of sizes all the way up to large wall murals.
You can also find laminated posters that feature the planets, the moon, milky way, dinosaurs and more. These would be great for a homeschool room or a bedroom! I am going to be purchasing some for our play room.
