Ok, well, I called Xbox support (again) today, and it turns out that the previous SR# did not match my profile. As such, they cancelled that one, and made a new order with a new reference number for me and will be sent in 3-5 business days (again). Ugh, the humanity. Although, they did add that the label will come with a box as well, so I don't have to scrounge around for one.
