How Hard Can It Be?

If you're selling something on Ebay or Amazon, how hard is it to put the item in a box, take it to the post office and mail it?

Is this another thing where I am an exceptional savant and everyone else finds it a baffling task?

PS: If you offer two-day shipping, and I select it, on day four I am canceling the order if I don't have a tracking number.

PPS: The Amazon seller in question is US-DEALS.  Avoid them, they don't ship in a timely manner.
