Well, another Black Friday has come and gone. And, much to the surprise of many (myself included), it did so with a bang. General consensus is that the Black Friday sales bonanza was a rousing success, and the numbers certainly support that: ShopperTrak reported that Black Friday sales increased 6.6% over the 2010 numbers, with a record-breaking $11.4 billion in purchases. More people were out and about — foot traffic reports show an increase of about 5% over last year, which is good news for the brick and mortar guys.
