The ink cartriges are working out just fine.
This is the second time I have ordered Ink from Great Offer Stock.com. You can't beat the price. I really recommend the 13 pk. which is what I was wanting, but for now is on B/O. So I opted to order only the 3 colors I really needed and go through very quickly. Again, you just can't beat the price and both times have gotten to me very quickly. Not sure about the issue of the ink cartridges flagging as expired? It doesn't seem to be disrupting the printing quality nor does it seem to be hurting my printer, so I will continue to use and order from Great Offer Stock each time I'm in need. :)
