Stem Education Products

As the stem education developing so fast .more and more stem products come out.

Just as LittleBits, makey kakey,Sam Labs,very popular in the world.

But all of them are very expensive ,so many people can not offord it or do not want to pay for it.

So if some one can provide the same product with the cheper price may be bwhoetter.

But who will pay for them ?
