Americans are having to dig deeper when filling up at the gas pump. Average retail gasoline prices jumped 18 cents over the past two weeks. That's the first two-week rise since early August, but prices are still down from the same time last year, according to the Lundberg Survey. A jump in crude oil prices is the main factor behind higher prices at the pump. Crude oil is now hovering around $80 a barrel on hopes demand will pick-up in the future and as weaker dollar makes oil more attractive to foreign investors. In earnings news, Verizon added more net subscribers than expected last quarter. Although the telecom giant is losing market share to AT&T, the sole service provider for the popular Apple iPhone, Verizon still beat sales and profit expectations.
