Thursday night, shoppers went to Lebanon's Prime Outlet in their pajamas. The first 500 people who arrived received a free gift bag. One store offered 6 percent off some items.

In Clarksville, one woman fractured her knee while shopping at Toys R Us. Police spokesman Jim Knoll said that Amy Serna was trampled. She was taken to the hospital.

Serna told the Leaf Chronicle shoppers got unruly after the store delayed the midnight opening because it wanted police to get there before it let people inside.

Toys R Us was unavailable for comment.
