"Canon BCI-6 8-pak"
The Canon i9900 requires all 8 cartridges which, when purchased seperately from normal sources may approach $100. Purchasing the cartridges in a combo pack saves a significant percentage.

The cartridges are original Canon. Other cartridges may be obtained for less money, and may be a reasonable substitute, but for those wishing to only use original Canon ink, this method of replacement is very desireable

"ink"
everything we ordered has been great.
the price I paid for 8 colors was the price of one at office stores!

"Always use Canon Ink"
I work in computer repair, and it is always best to use the company ink. Frequent use of refills or offbrands can cause print head damage. And if you switch back and forth from Original ink to offbrands/refills, you can see a drop in color quality. I have seen a few printers come in where the ink heads were blocked because people were using inferior inks. They may be cheaper, but in the long run usually means having to get a new printer faster. Not so bad if you are buying a $60 dollar printer, but costly if your printer is $400.

"Couldn't ask for a better deal!"
I usually purchase this set at least once or twice a year. It is such a good deal. You are getting genuine Canon ink. With my previous printer, I had bought cartridges with the "compatible" ink....and ruined the printer. Now I stick to the genuine stuff. These cartridges are anywhere from $10.99 to $12.99 in my local community, so to get these for less than $10 per cartridge is quite the deal.

There are colors which are used up much faster than others, such as the PC and PM and black. I end up going down to a local store and shelling out the bigger bucks.

Wish they would also sell multi packs of the individual colors at these prices!

"Great, but Pricing is HIGH "
I'll keep this short. The inks are great but not worth the price - unless you are soley printing pictures. Stick with the generics. They last longer and cost less.
