Received my Amazon order Apple Watch Series 5. Ordered the preorder date and received September 29. I did get on chat last Monday to ask what the ship date would be. They informed me it would be by Friday at the latest. It did ship on Friday.
Also for those still waiting, I received a $5 courtesy credit after the chat. The employee didn’t tell me about it but the next day when placing another order I saw the credit, which I assume was from that chat about the watch.
