Best Buy, GameStop and DollarTree Report, Jim Cramer's Gas Play

The earnings keep rolling out as retailers kick off the fourth quarter -- mostly -- with a bang. Before the opening bell, we'll get earnings from Best Buy -- which braved a tough slide, and has packed on more than 30% in the last six months -- as well as DollarTree, which is now delaying its big deal vote until December 23. Once the market closes, we'll see more numbers on the way, from GameStop and Gap. Plus, Jim Cramer is still gassed up for shares of Royal Dutch Shell. The company saw shares take a big dive when oil fell, but trading at a discount to peers, Cramer is looking at double-digit gains.
