I have been using it for almost a year. It is no cheaper than using USPS. They win you over by offering you $50 in free stamps. Try getting it. I emailed them and told them I never got the offers they offered to get me to use them. So, now I just use USPS and it seems to be going much smoother. I also have an Apple computer which is not compatible with stamps.com so I have to wait until I can get on dh's computer to do postage. Goog luck if you go with them.
