Manufacturing might

I am amazed at how good China is in manufacturing everything that was ever to be made. Especially toys. Pretty much every toy you can buy - both in stores and foot paths, are now made in China. I bought a little plastic bird, fitted with a motion sensor, a speaker and a little 'button' cell, so that it chirps when it senses any movement near it. They can make it in a huge factory somewhere in China, ship it all the way to India, possibly Chennai, transport it on road to Bangalore, distribute to stockists, resellers and foot-path vendors and they can still sell it for a meagre 20 Rupees. What should be the cost of manufacturing the toy? At what price can they sell this toy in the town it is manufactured at? While this is terrific, what is even more amazing is that if you want to replace the battery in the toy, you will need to shell out 40-70 Rupees. Do your math now!
