Do distributors/breweries dump old stock in new markets?

I was very fired up when Green Flash started showing up on shelves in WI earlier this year(2013) and got some Le Freak ASAP. Popped one open and it didn't taste anything like I remembered. I looked for a date on the bottle and found nothing, but my Hop Head Red had a bottling date from 10/2012. I checked the Green Flash website and read that they started bottle dating "all" of their products as of 5/21/2012. I checked 3-4 other shops in the area and none of the Le Freak bottles had dates on them. I e-mailed Green Flash twice to find out if Le Freak was actually being dated or if their distributor was getting rid of Le Freak that is past its prime, and have not gotten any response. I had noticed this a couple years ago when Alaskan products hit the shelves, most of the products were within a week of their "best by" date.

Do distributors/breweries see a new market and feel they can get rid of their warehouse of old product knowing that people will be so eager to buy it? How much interaction does the brewery have with a distributor once their product leaves their facility?
