Blame a postage increase, weak economy and more shoppers making purchases online. By David Sharp. AP photo Friday, Nov. 23 BLACK FRIDAY NEW YORK â¿¿ With Black Friday, you never know what you're going to get. Some years during this annual shopping rite of passage, shoppers line up in the wee hours of the morning to get TVs. Other years, the toys are the objects of their focus. Sometimes, things go off without a hitch. Other times, there's lots of pushing and fights break out. Either way, the official kickoff of the busy holiday shopping season is always a moneymaker: It's estimated that sales on Black Friday will be up 3.8 percent to $11.4 billion this year.

The National Retail Federation will release sales for the first weekend of the busy holiday shopping season on Sunday. Stores are hoping sales numbers will show that Americans are spending freely despite worries about the job market and a package of tax increases and spending cuts known as the "fiscal cliff" that will take effect in January unless Congress passes a budget deal by then.
