Ever try to ship via courier? It's a miserable experience. Eats up an average of 30-60 minutes setting it up, then you have to be at home at a specific time.

I imagine it works great if you have an account, volume, and dedicated staff + shipping area. But for consumers, it's not tempting.

I've donated some items I could have sold due to the annoyance. (You might think that would be a better outcome, but most of the items were pretty specific, and unlikely to find a good home through donation)
