I have an HP printer also, we usually get one of the twin packs from Walmart or one of
the Office Supply places that take the cartridge trade ins.
It's a color printer/scanner/copier, so the black cartridge always goes the quickest.
I also try to not print something unless I really need it.
I was wondering if those Walgreens refills worked, I almost did try it a couple of weeks ago but didn't.
