All round good choices! Just to clarify the difference between second and third, second item you always find it at a lower price, and no it doesn't mean it's starting to rot. But it doesn't necessarily mean it will always be top notch either. Just average, subject to the luck of the draw I guess, sometimes better sometimes unremarkable. Always cheap.
Third is anytime you eat some thing. It doesn't necessarily mean you purchased or cooked it. Maybe you were invited to an event or to a friend's dinner, well, if there is pasta there your portion will be incredible even if it was cooked in the same pot as everyone else's. If you give your portion to someone else, they will not taste this benefit but the mundane version instead.
