Walgreen's Inkjet refill service - $10 for ink!

I hate paying $30 for a black ink cartridge for my inkjet printer. I tried the refill it yourself cartridge kitsand could never do it myself. Since it is only about a teaspoon of ink in each cartridge, even discount ink stores felt like I was overpaying. I was excited to try Walgreen's ink refill service, they take several types of HP empty cartridges and will refill them for you for $10 for black and $15 for color. This feels like a much more reasonable rate for ink and the cartridge is sturdy and usable. I tested it with printing on a quality paper document and I found the ink quality to be equal to the HP ink. There were no streaks or spots or spills. Before using refilled cartridges check to see if this negates your printer's warranty. The best part is the refills are ready in minutes.
