Upgrade your printer and continue to refill your own ink cartridges
I just had my HP 8600 document feeder fail. This problem part cannot be ordered for replacement, and to have it repaired will cost almost $200. Well a brand new one on sale is only $250. And better yet, upgrade to the HP Officejet Pro 8630, since HP will no longer be manufacturing the 8600.
I have saved hundreds of dollars, refilling my own cartridges. I upgraded, after I learned that the newer model uses the exact same ink cartridges. So, I am on my third HP Printer, and I have purchased only one set of cartridges in 3 years. I have refilled my color cartridges at least 8 times. They need refilling more frequently than the black. (The black ink cartridge is twice the size.)
In addition, I purchased a three year extended warranty for $20 or $30. If anything happens to this printer in that time, it will be replaced automatically, and I will not have to pay for shipping.
In essence, I am in position to have used the same set of ink cartridges for 6 years. I only put my new cartridges in after I have refilled the empties. After the printer resets, I pull them out and put in the refills. So you see, my printer came with a set of cartridges, and I purchased one extra set, for resetting the printer after refilling the cartridges.
I suggest to really control your costs, consider buying a quality printer, that will be good for years of service, add a service contract, and refill your own cartridges. If you print as much as I do, you are realize a significant savings in the cost of ink.
I know that I have saved a minimum of $360. Add the cost of inconvenience and going to Walmart for refills, and you may be realizing a savings of $150 per year, just for refills.
Good luck, and plan ahead.
