My SS w/Classic Band has been "Preparing to Ship" since Monday and I finally had luck using the UPS "Reference Number" method to find it.
It is, in fact, already stateside, in a box, labelled and ready to be picked up by UPS.
I got a tracking number from the UPS site, plugged it into Delivery app.
Label is marked for a 4/23 pickup, 4/24 delivery.
Photo attached below for the inevitable "Pic or it didn't happen" post.
I know this has been covered in other threads but they way I got to it (because I couldn't until I set the date correctly):
"Track By Reference" on UPS.com
Put in the phone number you used with the billing address (not the notification number, if you set one)
Date range: 04/23/15 and 04/24/15
Your shipping zip
That was it. After trying FedEx and UPS over 2 days, finally got it after moving the date range.
