Wow..went to USPS to ship a 3-4lb book. was just gonna throw it in a priority box so i didn't have to buy a box or envelope. The cost for priority was $13!! I was like uhh no. So I walk out and go to UPS and it was about $5. Hehe. I don't see how USPS thinks they're going to make money by charging rates that make them extremely uncompetitive with their competitors! They're just going to lose customers especially any businesses that still ship USPS. What are they thinking??
