I'm trying to sell a few textbooks and I've never sold anything online before (except for right now though, because one of my books sold like right now and I'm excited about it!!). However, I'm a little unclear on how to ship the damn thing. My understanding is that media mail is what I want for textbook shipping if I go through USPS, but I don't know what to do with the package after that. I know I can take it to the post office in person, they'll weigh it, and take it or whatever... but I also thought you could also drop media mail packages in the blue post boxes even if they weigh over 13 ounces provided the mailing labels are bought from Amazon (who uses Stamps.com) or whatever.
Can you drop media mail packages in the blue post boxes even if they weigh over 13 ounces provided the mailing labels are printed off the internet (e.g. Stamps.com/whatever)?
