I can't say enough about how I appreciate this service. I send most everything flat rate and can purchase postage, print postage, and keep all my customers saved so I don't have to enter the information each time. I can read reports of when items were received and how much postage I used for the year for taxes. This saves me time waiting in line at the post office, especially around Christmas. Also, if I make a mistake printing the wrong label, I can get refunded if it shows I didn't use the label.
