Amazon Competitor Jet.Com Debuts With "Club Price Savings"

Jet CEO Marc Lore has e-commerce giant Amazon in his crosshairs with the launch of his new venture.

Online shopping platform Jet.com finally opened to the public on Tuesday. After introducing a beta site for select customers in the spring, Jet is now launching with a valuation of $600 million—and is rumored to be in talks to raise that number to $3 billion by the end of the year.
