I am back from dropping off my Amazon return, and what an adventure it was.
It had been several years since I'd returned anything, so I was surprised yesterday when they told me not to package the item, just take it to one of the authorized drop-off locations, show them the code that was being emailed to me, and that would be that.
Well, that was indeed that. I picked a UPS store. I walked in and only one other person was finishing up with one guy, and the other guy called me right over. I showed him the email on my phone and handed him the goods, he printed a receipt, and I was out of there in thirty seconds.
