Does USPS show package weight?

Okay, so, does USPS show package weight? Yes, they do! I've definitely seen it myself, numerous times. Where, you ask? It's in the "Transactional Details" of your tracking info. You know, when you track your package online? Dig a little deeper—it's there. Seriously, look! It'll list everything: how much it weighs, what kind of mail class it is (like Priority, or whatever), the postage price (always good to double-check, right?), and the addresses, both to and from. Just the other day I was tracking this vintage cookbook I bought online, and I was so curious how heavy it was, because it's a real hefty book. Sure enough, there it was in the details – 2.5 pounds! Which, I mean, explains why the shipping wasn't exactly cheap. But totally worth it, of course. So yeah, it’s there, don't worry. They don't just hide that kinda info from you. ????
