Ok, before you get your hopes up, the use of the word unimaginable was actually a literary device known as sarcasm.  You see, under the conventions of sarcasm, occasionally folks such as myself will apply an adjective to a word that is actually quite the opposite of the word's true nature.  In this case, prices right now--at least in the context of where we've been and where we're going--are about as imaginable as it gets. 

Implications, analysis, and relevent considerations for the rest of the week to be discussed shortly in the CLOSE.

Oh, and in case the sarcasm is not now readily apparent, those three lines would be PAR-Nertia Central. 

Imagine That!
