Inventories were crushed between Black Friday and Christmas. Combine this with the San Bernardino terrorist attack and fear over "Obama's gun control executive orders" and you have a small to moderate panic buying frenzy when sales are already high due to the holidays.
Another month or two and this should pass; it is almost a certainty that manufacturers are increasing orders and inventories going into the 2016 General election - there will be buying leading up to it and arguably, regardless of outcome, buying following it.
To answer the base question...no. After the Great Shortages of 2013 I decided I would never be without a reasonable supply of "stuff" again and have been steadily buying as availability and funds have allowed.
Well put...
