I knew they were worth something. As I do my Makati rounds from time to time visiting clients, every time I walk along Ayala Avenue, there are some people in front of several buildings holding empty ink cartridges with a sign stating that they buy empty inks. The first thought that came into my mind was, why are they buying it? Well honestly, up to now, I don't know why but my guess is that it has something to do with either refilling it or using it for those unlimited ink systems. Let me know why if you know.
