Address and Print USPS Certified Mail® Labels Online! This is a great post (and much better than the usual videos), but maybe the title line should be fixed? Baker previous featured an article on his own blog entitled How I paid off $15,000 in 9 months by selling my Stuff on Ebay.” 1st: previous -> previously? And the link is to a guest post on Baker's blog from last October…? This seems a little odd!!
Apart from the amount of postage the user wishes to purchase you should also set the ControlTotal configuration setting. This is the amount of postage that the user has consumed over the lifetime of the account. Sending ControlTotal lets the server know if you have the correct postage balance when buying postage. If you do not then it is possible that the postage balance was changed through other means (the user could have logged in through another integrated application to purchase or print postage). Initially it is returned by after calling GetAccountStatus. Thereafter, you can track the ControlTotal by adding the postage consumed with each print to the previous ControlTotal.
I've been to three different post offices at three different times (one for the save-the dates in December, one around Valentines to get cute stamps for RSVP cards, and then once recently for invitation stamps). All three times, the person working was very helpful and didn't act annoyed or anything at all my questions and wanting to see different stamps - so don't be afraid to politely ask!
As the article suggests, USPS flat rating shipping can often save merchants quite a bit of money. Many merchants, like those using open source software platforms like Magento, are faced with the problem of accurately determining if their products fit into a given flat rate container at the time of checkout. The challenge is determining if the cart items actually fit into the given max weight and dimensions of the flat rate container.
In other countries such as the U.S, the process of buying stamps online and subsequently printing the same is outsourced to authorized vendors such as eBay. What you need to do here is to locate one of the many authorized vendors to establish the stamps value and proceed from there. The process is as simple as visiting the official website of your national postal service and getting the contact information of the authorized vendors and you will be good to go.
