Refill.....Refill.....
I've been doing it for almost 2 years. My current HP1823 Cartridge I've already refilled twice, at a cost of about $2.50 each refill.(cost for 3 colors). In 2 years I only purchased 1 black cartridge. Refilled the original that came with the printer about seven times.
And if your wondering, I do my own benchmark comparison to the new cartridge. I always print a pic with the new and again after I refill. Always perfect. Color refill is not always 100% successful, but I'm getting there. Black is always 100% successful. More people need to do this. Cartridges are just toooooooooo expensive.
