Primes shipping advantages are 100% hit or miss. They no longer honor delivery estimates. In tgier efforts to save a buck, they implement private shipping companies that send your shit half way around the world and back, when your item started 100 miles away. I'd say about ~50% of my prime orders take 8-10 days when they advertise 2 days. I bitch, and they keep moving the goalpost, changing thier promises. Over and over. And, prices now are on par with so many other sellers. There is very little reason to continue using Amazon.
