do you sell coffee containers that go into a little machine to make coffee

If you mean the keurig cups, yes, they sell it.

I'm not sure if they do sell those.

Like the k-cups? I think so. The Dunkin donuts ones, the Kureg ones, and I think they have the Starbucks ones too. That's just me talking. I'm Not a Safeway representative... Not yet LOL. I don't think I'll ever be also haha.
