When I first got into Stamps.com, I got it for what was then my business, HartBeat Vending, LLC. It was great then for printing out stamps for mailings. Now I still use it for my personal mail, e.g., when I mail my rent checks to my landlord, I use it to print out the envelope with the address and postage on it. It works out great, as I don't need to go to the Post Office to get stamps, etc. I can just print them out on my computer, or print an indicia directly onto the envelope. I love this program.
