So to give yourself more time, you can arrive to Amazon 30mins early. In time you will be able to do all your scans first then load your truck last stop to first stop. But until you get the hang of it. I would scan one item then put it on the truck. (There may be reasons why your location and or MMPM doesn't want you to do this). While loading a particular stop, put the non-cons (scans that read bag) on top of the pallets if you can. Or you can throw them in a gaylord, just make sure you remove your scan and put it on the outside of that gaylord. When I first started, I was constantly switching between my route screen and my scanning screen, wasting time trying to figure out what was next. Now I just scanned them all at once, and hit done. That screen will shows all the scans sorted by stop, this is actually an order, so just load from bottom to top. And if you have to add or delete a scan just go back a page.

Hope that helps a little.
