New strings are the cheapest way to make a ukulele sound better. They go dull with time, and most players hear it as a loss of brightness before they notice anything else. There's no rule about how often to change them. Twice a year suits most people. Order the set that matches your size, since they aren't interchangeable.
Every accessory ships free when it goes out with a Honolua Ukulele. On its own, any order over $100 ships free as well — under that, it’s a flat $14.99 across Canada and the US.
