Shadowbox is a cross-browser, cross-platform, cleanly-coded and fully-documented media viewer application written entirely in JavaScript. Using Shadowbox, website authors can display a wide assortment of media in all major browsers without navigating away from the linking page.

What about the case where most products don’t have offerings, or the offerings don’t have merchants, vel cetera? If this were a frequent case, and this were inner-loop code, I might introduce a global empty object in order to reduce the object instantiation overhead (which happens right away) and the GC load (which shows up over time).
