This is extremely unusual for me and I don't think it's ever taken this long for me to receive a domestic order. What's even more frustrating is it was shipped with priority mail which, although I know is not guaranteed, should definitely not take a week. The order was placed late sunday night or early monday morning last week and it's the next monday and nothing's arrived all day. ...-_-
Happened to me recently. Shipped on 17th, didn't receive until last Wednesday.
