For the last YEAR I've been using Stamps.com to print my postage.
It costs $16.99 a month JUST for the privelidge of having Stamps.com.
Now today I find out you can print postage for FREE on the Postal Services website!
The only difference is you can't print stamps, or postage directly on an envelope, but the main thing I print is shipping labels so that doesn't really matter.
Now I gotta figure out how to cancel my Stamps.com account.
It has a few nice features. Being it's own software you can keep a contact list. It let's you print stamps, or print postage directly onto an envelope.
