I live in Los Angeles and have had the complete opposite experience. Been a prime member for 4 years now, I order from them all the time, and shipments always come on time with no problems whatsoever.
I live in LA as well. While most of my Amazon purchases arrive on time (and even occasionally early!), more of them have begun arriving late. My Prime Day purchases, for example, were originally supposed to arrive same day...but are currently on track for Saturday and Sunday. I could have just stopped by Best Buy on the way to work.
