Hello, comrades. I wrote a tutorial two weeks ago about the usps shipping because I believe it would be helpful for both sellers and buyers to get a better understanding about the shipping inside and from the United States. I am not an employee in the post office, so the article is based on my analysis of the current drafted postage and my personal experience in shipping packages. I would be greatly appreciated if you would read the article, give me any feedback you think would make it better, and correct if you find any info is inaccurate or wrong. I hope this article will assist buyers and sellers at all levels in our community. You could visit the article by clicking the link below or go to my personal journal.
