From Argentina, here's a lady who has a really great chocolate factory and the packaging of his production makes his weapon to compete in the market.
With a Maestria, prepared with the automatic carriage for the production of tablets , has invented real marketing systems to sell more her chocolate.
An example are these postcards that once you have chosen the image are filled with a chocolate tablet and are ready to ship or by hand through couriers.
It speaks even local television and then success is assured.
