So i'm about to ship a box to a person but the shipping is pretty high if i choose priority mail, so i was wondering if there's another option that i don't know about.
The box contains mainly video game systems and a few games.
Sometimes it depends too. If you're only shipping something fairly nearby (like within a few states), Priority will be cheaper than Parcel. But for cross-country shipments, Parcel is the cheapest as far as I know.
Just be careful when mailing parcel post, as it only covers shipping one way, where the other shipping methods cover it both ways. Like if somebody accidentally gives you the wrong addy or something and the package comes back to you, you will have postage owed before you get the package back.
