Ordered it this morning. Got an estimated arrival of May 8th so they may be treating this as a pre-order and not shipping immediately. However the guy on the line said he doesn't know for sure if they are planning on stalling shipments or not, but if they do ship today or tomorrow I should get it much earlier.
A few hours later I notice free overnight shipping on the site on the S4, but of course it's for new customers only. Called back the first time to try to get free over night shipping, the lady was something else. She said she can't cancel or change my current shipping order and just said to wait until the ground shipping comes, deny the shipment and it'll get sent back, wait for them to receive it, and then she'll send it back over night for free. She was clearly confused. Called back got another lady, she quickly said any of the shipping offers are for new customers, but waived my shipping fee.
