For the first time since 1949, Black Friday sales featuring items sold at cost or below are actually legal in Oklahoma.
The state passed the Unfair Sales Act in 1949.
It banned retailers from selling items for less than 6 percent more than they paid for them.
That's when the state legislature took action and changed the law.
In 2011, Oklahoma Attorney General Scott Pruitt issued an opinion exempting Black Friday sales, but the law remained on the books until earlier this year.
Now, most items can be sold at cost or less, up to 15 days in a row, as many as ten times a year.
Some items are exempted -- gasoline, medications, lumber and groceries, specifically.
It's unclear whether Black Friday sales in previous years were affected by the 1949 law, but most retailers -- especially large, national chains -- applaud the new rules.
