You can differentiate it by size and also by venue (i.e. bars). I've seen some crazy bar prices but I can't remember them right now. The most ridiculous thing I have seen is a $38 DFH & Bruery Bottle (that was knocked down to $27 recently). However, I have seen $22 single bottles (a signed Black by Mikkeller). Also, there are some $36+ Eclipse bombers.
