Much better value than individual inks, As others have said though it would be better to get the value pack cheaper without the 'free' paper. I have bought a few of these and although the HP blurb says it is the right amount of each ink in each cartridge (each one holds a different amount) to print out the 150 cards supplied, it never is. I always run out of 1 or 2 inks long before the paper runs out. I have started giving away packs of paper now I have so much even though I print most of my colour pages on this 10 x 15 cm stuff.
Buy this, but you may need to buy the odd Cyan cartridge to keep it topped up till you need another pack.
