I second this recommendation. The JINS experience (at least in Japan) is amazingly convenient, pleasant, and affordable. I sometimes drop in to pick up an extra copy or two of a pair that I like, and get my current pair tuned up. They'll keep your lenses in their system so you can drop into any store.
