With over 400,000 subscribers, Stamps.com is revolutionizing postage for small businesses, home offices, and individuals eager to escape the hassle of long, time-consuming lines at the local post office. Their monthly service and account origination fees include the necessary software and a five-pound scale that hooks up directly to your PC. You can then buy and print all the necessary postage you need online, and are eligible for specific postage discounts that you can't get online. Stamps.com works in partnership with the US Postal Service, and all printed postage is official USPS tender. In addition to providing postage, Stamps.com can track your package for you, validate your delivery address, and give you estimate of delivery times.
