Here is an easy way to earn 750 United Miles. 

MyPoints is the pioneer and leader of online shopping rewards. Through simple online purchases from hundreds of retailers within the MyPoints network, members earn rewards Points from every transaction made. Members can redeem their Points for gift cards, travel miles or cash back. MyPoints has grown into the most established membership rewards site where online shopping and rewards incentives are synonymous with great deals and customer loyalty.

I signed up for a MyPoints account and hope that the bonus miles post. I might look a little more into the site and see if they offer better options to some of the other shopping sites like Big Crumbs, FatWallet or the airline eShopping portals. Odds are that I will probably opt out right after I get my bonus.
