How does ComboInk sell this stuff for so little?  Especially since they guarantee their products for one year.  I’ve still got nothing but good things to say about my HP B&W laser jet or FirstBorn’s HP color ink jet cartridges and I think I’m on my third cartridge now.  Everyone else seems to share my experience.   I was talking to someone who buys at Staples(!); weirdly enough, she was complaining about quality issues with actual HP cartridges.  And another person gets those Walgreens cheap refills with a wide range of results, most unsatisfactory… Free shipping on $50+ orders – otherwise it’s only $3.99.  What’s not to like?  And if you got a new printer over the Holidays, you will definitely want to stock up.

Here’s the ComboInk guarantee:  
The cartridges we offer are 100 percent risk-free. We can be so confident about them because they are from some of the most renowned companies. We offer a One-Year Money-Back Guarantee on all of our ink cartridge products, if you are not 100 percent satisfied with its performance.
