I have been getting refills for my Canon MG5220 printer from Nancy here at Cartridge World for about a year. I could get replacements for these cartridges at Walmart for $17.00, but I would rather get them from Cartridge World at $10.99 per refill. I save on average about $18 every time I stop by. The cumulative amount I have saved over time must be something in the $100's. I have looked around for other establishments that would provide a similarly priced refill, but to no avail! I have NEVER had any problems with cartridge leakage such as the previous post mentioned. From my experience, these refills last a long time, and the quality is the same as if I had purchased a new cartridge. Also, Nancy is awesome, and she lets you spin the wheel for a gimmicky little prize, which is strangely exhilarating (yes, I am a grown woman). Love this place!
