Amazon fulfillment provide 2 cartridge package- only one works.

I've had my printer for years, and I use dozens of the same type of cartridge per year. This time I ordered at 2-pack of HP 62 black ink. Strangely, the first cartridge is fine, but the second one cannot be accepted by the printer. I've tried other cartridges to ensure that it is only this one that is faulty. Every time I try to install, printer tells me to "remove and replace to insure proper installation." Again, it's not my printer. It's just the ONE cartridge. Bummer. Ink isn't cheap. Furthermore, the return window closed (it's been exactly a month), and of course I couldn't have known that the 2nd cartridge wouldn't work until now. I feel Amazon should replace with a working cartridge under these circumstances, but apparently it's too late. Crummy.
