Another "free marketer" playing free with "full information"

Last summer I had to replace my computer and did so at BestBuy. In September I received an email that I had a $45 reward certificate that expired on 4/14/2012. Then before Christmas I received an email that my rewards would expire by a certain date. Today I received another email "Last chance: Use your reward certificate before 01/07/2012".

I think the message really means the specials that will be available for reward points will expire in January. But you wouldn't know that from the wording.

Whatever, this is not a true free market where the buyer and the seller have all the information they need to make a good decision. At least, I am free to not be in the market, if you ignore possible forfeiture of my "reward points".
