The level of vibrant speculation from some folks about this is somethin else. Express shippers like FedEx can receive and forward inspection notices because of the backlogs they generally cause. It doesn’t seem suspect in and of itself.
As some mentioned, can take many more days or weeks (or in less common circumstances, much longer still). Lucky when it’s audio toys and not perishables. Good down time to reflect on being lucky enough to have time and option to type the discrepancy online, hey? 😉
Hope it’s a good piece of kit when ya finally get it!
