Is taking more than you need stealing?

Say, for instance, from some convenience store, I knowingly take more free ketchup packets than I need with the intention of having extra ones for camping or something later. Is this stealing? I mean from a legal point probably not and I can live with myself for doing that once in awhile but sometimes I feel a tug of guilt. Anyone else?
