Hey, if I may plug a website briefly, https://pirateship.com/ is really good for shipping stuff from home (via USPS).
Lowest commercial rates (cheaper than post office walk-in or USPS website), good UI, minimal required setup.
Also, best URL.
@starkatt That sound really nice. When I sold off my RPG collection I was constantly using a postal scale and tape measure to estimate costs then trekking down to the post office to mail things.
Made a months rent doing it at least.
@starkatt yay, another thing that makes paypal unnecessary! if only this were, y'know, part of the USPS website...
Also I love USPS Priority Flatrate. It's a little bit more expensive than first class package, but it's tracked and you can print postage at home without a scale.
And, critically, the (high quality) envelope/box is included as part of the price so you don't need to figure out your own packaging. You can pick up however many flatrate boxes you want at a post office and just wander off with them to use later.
