I always pick up all that's on the shelf for my cousin of the organic sugar.
Small bottles or packages of aspirin, cold medicine, vitamins, allergy meds., some hand tools, synthetic motor oil for generators, tape, twine, LED light bulbs, packages of party balloons for target practice, alcohol for medical purposes, bandages.
