Canon CLI-8 4-Color Multipack Ink Tanks
It’s misleading for Amazon to bundle a CLI-8 4-pack with a PGI-5BK 2-pack. These cartridges are for different printers. And, all Canon ink is outrageously expensive.
The ink I ordered for my Canon printer came so fast! It was practically over night. Great job!!
The product works; big deal.
What is really important is the cost of the product — INK! If one converts the few thousands of a litre of ink into gallons, this ink costs THOUSANDS of dollars per gallon. And some people think the oil companies are gouging the price of gasoline!
I was very happy with the purchase until I had to change one of the colors and the cartridge was defective.
So I feel I was shorted one cartridge and will I encounter more damaged ones as I use them up.
When I bought this ink it said it went to my printer when I got it and look at it it said it didn’t now I know that I order the right one, so it has to be mistaken in the shipping because I know I got the right one, Now I am stuck with this ink that doesn’t fit my computer and lost 39.99 dollars actually 42.00 an change so I am kinda mad bout this.
