Even that thread is strange to me. There’s some people saying it takes 5-7 days to get delivery to Raleigh, while there’s also multiple people disagreeing saying they get 1-2 day delivery to east Memphis (less than 10 miles away).
That’s exactly what people are reporting. It’s hard to suss out exactly what is different about these areas but there’s no doubt that some people get much better service from Amazon than others.
