How it works is by using the promotion to sign up for the Stamps Free Trial.
With the trial, you get things like $55 in postage coupons, a $5 supplies kit, and a 4-week trial. You also get, to me, the most important part -- the free digital scale. The scale allows you to skip the post office by not having to go to the office just to weigh a package, you can now do it from home. The trial also lets you print your exact postage right from your home computer. No need to go to a physical location just to do that and no need to waste postage by using preselected stamps. Finally, all you have to do to completely forgo the post office is by calling or scheduling online someone to come pick up your packages for you.
I love the simplicity of it all with the low price!
