It's not really a racket (other than the fact that inks now cost more per ounce than fine champagne). There's a whole science behind it, see this link for more of what you should know and even more you don't need to know. Check especially the "Fade Factor" article if you want your prints to last more and a year or two. All inkjet paper is coated with different formulations of a substance similar to clay. Different company's inks are formulated for different types of these coatings. There are also "profiles" for each major manufacturer of printers and papers. There really *is* a lot to know if you're going to be using off-brand paper (and inks). That's why I said it's best to just stick with your printer's brand. Also, if you search for "kodak" in that printer forum I linked you to in my first post, I think you'll find a lot of complaints about their paper with different printers.
