Jet.com is a new site that is looking to try to compete with Amazon. To do this they are going to charge members for an annual membership ($50). I am assuming it will be similar to Amazon Prime. Right now if you join you can get a FREE MEMBERSHIP.

Join the Jet.com Pre-Launch to get a free 6 month membership. The more people you refer the more perks you can get. They are offering early access, a free one year membership, a free five year membership, a lifetime membership and even stock options to people for referring friends.

The Jet Insider program ends Feb 6th, 2015 so if you want additional perks, start referring.
