Very helpful to know that you don't have to run to the post office to pick up those much needed stamps (that is, if you don't pay all of your bills online or if you still write letters). It's amazing how technology has removed much of the need our family had for stamps. Don't think we have used one since they were 37 cents!
Anyway, USPS.com provides a postal store and you can even use their "Click-N-Ship" feature to send priority packages from home. You can also buy stamps and many other mailing supplies. Such a value for businesses and individuals and cuts down on those lines when you absolutely have to go to the Post Office.
