Query: Unsatisfied

I thought that I would save a little money and contribute to saving the Earth by buying refurbished cartridges. However in the end I wasted both time and money. I used the cartridges in my printer one time and after that I could not get any more use out of them. I didn't even go through the trouble of returning them. I wound up just buying cartridges new at the local Target.
