That's exactly how USPS is, you go online, enter the address, the weight, the size of box, you enter all your packages in, pay all at one, you print the labels and you can even arrange for your mail carrier to pick them up at the house. USPS also offers free priority mail boxes in many different sizes. Even ones that are flat rate priced, so everything you can fit in one box for one price no matter how heavy it is. Then you can go into your account and track all the packages in one place. They make it ridiculously easy because they don't want you and your 900 packages clogging up the line inside the post office.
The international form is pretty easy to fill out, so I have no idea what "help" they'd need or why they'd get turned away at the counter and have to go back. Aside from the fact that they are idiots. And they supposedly shipped stuff to Krispy Smores and Holy Moly all the time, so I don't understand why they didn't know international costs so much or how to fill out the form.
Tim says that UPS wouldn't take one of the boxes because it would get stolen? I don't understand what that means. Like they packaged it in a box that made it seem like something good, not tit they've kept in their junk room for 8 years? Why not just cover up whatever the box said?
