A few attempts to make some code less dense. Thoughts welcome.

@CocoaKevin Exactly that. It's unreadable, has no error path, hard to comment, hard to convey thought process

@ericasadun How about parsing the json into a Product struct first, then add ShowPrices & CheckRatings as methods on the struct?

@ericasadun I would break it down a bit. Have a struct that knows how to initialise itself from JSON rather than just Parsing and printing.
