Good: Price, customer service, fast shipping, EVERYTHING.. Bad: No complaints at all!!. Improvements: Company is the best out there for ink. No improvements are necessary!. Other: I absolutely love this company. It has it all, excellent price, wonderful and helpful customer service reps, fast shipping, you name it! They have been more than helpful in helping me pick out the right ink for my printer and of course, at unbeatable prices. I don't think I could ever get ink from anywhere else except Castle Ink anymore; it's that cheap! Really makes a difference in how much money you save. :) Very satisfied customer!.
