Priority mail has a flat rate price; $7.65 is the lowest for a package.
The rate increases nearly everyone else pays can be attributed at least in part to the unnaturally low rates AMZ has negotiated (OK, strongarmed) with carriers.
I just got these 6 Grandberg sharpening stones for chainsaw sharpening in 2 tiny bags and a small Cool Grind stick, and the box they came in I thought was over packaged and that makes me wonder if that doesn't have an affect on higher shipping charges. The total item cost was $15.75, Shipping was $7.65 flat rate, those few items could've easily fit into a small padded envelope.......
I don't know that a small padded envelope would be any less expensive. Depending where it was being mailed from it could actually be more. The flat rate boxes are generally a really good value. Plus, as mentioned above, it makes things much simpler for the shipper to have less options, which allow them to not have expensive Handling charges besides.
Tell me how I can order a small electronic part from China for low dollars, and it is shipped for free from China via "China post" and comes in a small flat bubble pack envelope. How does that work?
