Police had to be called to two Indianapolis, Indiana, Kmart stores early on Thanksgiving morning.
Shoppers waited in line overnight to get vouchers for 32-inch plasma TVs, priced under $200, reports TheIndyChannel.com.
However, tempers flared outside the stores when some shoppers began selling their vouchers for a profit and others were too late to get vouchers.
In Sacramento, California, a Kmart shopper threatened to stab people outside the store, where a line started forming last night at 2 a.m. with hundreds of shoppers cuing up, reports Fox 40.
When workers came outside to give vouchers, the crowd began yelling and screaming obscenities.
