My HP printer stopped printing because the yellow cartridge was out. Every time I tired to print it would error out saying the yellow cartridge needed to be replaced. So I go Costco to buy the cartridges and of course they wouldnt sell just the yellow, I had to buy the whole pack. The whole pack cost about 70 bucks. Then I go to look at how much an entire printer cost. I found one for about 70 bucks. Now I know HP needs to make money but WTH.
