You are sounding a lot like that which you disdain. Simmer down, take your own advice and accept there are differences of opinions including your own.
I believe you believe you got a great deal on the cartridges. Are there third party prefilled cartridge inks of good quality? Yes. Druckerchannel.de has done comparisons over the years. Unfortunately, not all of these are available to everyone. Additionally, refilling OEM Canon cartridges with known high quality inks is even more cost saving (not to mention an enjoyable activity). There is a measure of comfort that Image Specialists ink, for instance, performs consistently purchase after purchase.
Forum members have dealt with aftermarket inks from a variety of sources over the years and found that quality and/or print longevity are, in general, oftentimes lacking for the hobbyist photo printing. Casual printing may be perfectly fine depending on the perception of the user.
