Postage Stamps Increase, yet none available?

Well today is the day that postage rates increase by 2-cents. It came to no surprise that when I went to pick up the new postcard stamps last Friday that the new postcard stamps were not in. This is the same problem I encountered when they raised post rates last time. Their new full-rate stamps were available, but they didn’t come in to around 10 days before the change. We must not forget that the post office is a private entity that is over-regulated from the government and shielded from competition.
