Today I bought a jar of 'home-made' apple, orange, ginger, cinnamon and cardamom jam from the nice café/store around the corner (where everything costs four times the normal price because they make it themselves).
I wish I hadn't bricked my phone and could post an image of the metal-clipped, rubber-sealed, two-part glass jar it came in (wonder if they want me to return it?).
I have a similar place near me. I consider reusing those jars myself to be my little way of amortising the higher purchase cost somewhat...
