I bought 2 pair of ink cartridges through ebay. They sat on my shelf for 2 months until I needed them. I put the first pair in & in a week they dried out. I put the second pair in & they were dry right from the start. I tried calling them, but they don't answer. The recording says to email through the purchasing market place. I did so, but no response. Ebay wouldn't do anything because it was past 30 days.
