An easy way to enable your greenpoints account to donate miles to another account is to purchase goods from ourhouse.com. They have a $15 rebate for new customers and at least when I ordered they had free shipping. I spent $4 got a cool toolbox earned 80 greenpoints and enabled the transfer feature in my account...then i promptly gave all of my greenpoints to my wife's account and ordered more mileage certificates....btw ourhouse.com also participates in the mypoints program so I earned mypoints as well as greenpoints...but that is a story for a different thread
