OEM is probably best - wish they were cheaper
If you have to buy more than a couple of the inks it makes the most sense to buy this multi-pack. Great OEM ink from Canon - just wish it was cheaper.

Great price, great quality
I must say, this is a great value for original Canon ink cartridges. I think they are like $12 to $13 each at best buy or circuit city. I found a couple at sam's club for $9.90 a piece but that's still not as cheap and i couldn't get every color.

Also, I've tried the cheap generic ink cartridges and they simply don't work. Ink is one of those things that is worth paying the extra money for and buying from the manufacturer. The cheap ones dry up quickly or leak all over the place and streak, potentially ruining your printer.

I've gone through two sets of these so far in my printer and they have worked flawlessly all the way to the end.

Canon ink for photo printer
Great price, and prompt delivery; this is cheaper than buying individual tanks from the office stores, or just buying a 3 pack from huge warehouse stores. I tried the generic inks once and it smeared on my photographs and almost ruined my printer. This is my second 6-pack and I am happy with the price and convenience.

SAVE MONEY, BUY GENUINE CANON INK
Save your money and buy Canon ink. Years ago I bought a Canon 6000D printer and after the ink tanks ran dry I refilled them with third party ink. I didn't see any difference at first but slowly the colors changed. I started seeing a slight magenta cast, but continued to refill thinking I was saving money. A few weeks ago I bought a Canon Pro 9000 printer. I was shocked to see the beauty of my first print. It was a photo I printed on my Canon 6000D just days before I got the Pro 9000. What a difference. No magenta cast, bright yellows and greens, and an orange that would bowl you over. I then replaced the ink tanks in my 6000D with genuine Canon ink. After cleaning the heads I printed the photo again. Night and day. The quality of the 6000D print came close to that of the Pro 9000. The magenta cast was gone, all the colors were rich and clean. The tanks with third party ink is now in the garbage where they belong. I am now thinking of the wasted paper I used trying to get one good print using the NON Canon ink. I would have been way ahead, and saved money if I used Canon ink in the first place.

No substitute for Canon printers
I own a Canon Pixma, I6000D. I've been a photographer for over 15 years. My first printed pictures (on Photo Paper Pro) from my digital camera were better then most prints that I had made with actual color paper.

I've used other printer inks, and other papers. Canon's color is amazing, accurate, and the best.
