So you clearly have the brains and aptitude to figure out how to arrange for a pre-paid box to end up shipped.
It's not that I can't figure out how to ship a box, it's that where I live, shipping out a box is a huge inconvenience.
And this is relevant because?
Getting home from work at 1 AM is relevant because that's when my availability starts, at the earliest.
Why the hell would you need to take time off work for this? This is the sort of thing I could manage to take care of in under a minute, without going out of my way.
When the nearest town is 20 minutes away, no it's not something I could take care of in "under a minute". Where I am the post office doesn't pickup packages at the door. I'd have to drive into town, which is a 20 minute trip one way.

I'd have to take off of work because it would be about a 45ish minute task during post office hours, while I'm usually working. See, not everyone lives in the city like I'm assuming you do.
Hell, I could walk into where I work, leave it with reception and say "company shipped me an X by mistake, they're sending a courier to pick it up", and they wouldn't bat an eye.
Must be nice to have an office and a receptionist. I have neither.
I could leave it with my neighbor. I could ask a friend who goes by a courier on his daily commute to drop it off for me.
Yeah, let's just ask my "neighbor" to take 45+ mins of their time because some company screwed up.
Let me guess... if you tried any of these exceedingly complicated solutions, the receptionist, neighbor and friend would all go off on you about how they work 70+ hours a week, and don't have 5 minutes to spend on a favor since their time is very precious to them, and why should they lift a finger for anybody but themselves anyway? In fact, they ought to invoice you for the time you wasted just asking them to help out? And besides, if the company doesn't want to send a courier to your house at 2am on a sunday morning, well then clearly they can fuck off.
Pathetic.
Not everybody has the same living conditions as you do. I've sacrificed some conveniences in exchange for other lifestyle benefits. Bottom line is that if you ship me something on error, and want it back the onus is on you, NOT me. I'm not going to sit around waiting for you to pick it up, and I'm not going to lose an hour of pay and burn $8 in gas just to return some package that you sent me that I didn't ask for. Even if they paid the postage, I'd still be out ~$30 for their mistake just by taking the time/gas to return the package.
