You can do this by signing up for the coupon with a Stamps Free Trial.
What you get with the trial is a free digital scale that you can use to weigh your packages. You no longer have to try and guess how much your items weigh to figure out postage. It's readily available to you now.
With the trial, you also get to print your postage right from your home computer. Just as you don't have to go to the post office just to weigh your item, now you don't have to go to the post office just to get the correct amount of postage.
The last step to skipping the post office is once you have the item properly weighed with the correct corresponding postage, all you have to do is go online or telephone your post office and schedule someone to come pick it up.
How amazing is all of that? You can get all of your post done with a cup of coffee in your hand and a smile on your face.
