Oh, mine don't exist yet either, I just know where they are both coming from. Beck, the KFL+ has been in "pre-shipment" since early yesterday morning! Which means it either wasn't scanned when picked up, or the seller hasn't actually mailed it yet( those usps scheduled pick ups are tricky like that , they make the receiver THINK it's been shipped).
Another note about ups,FedEx,usps; the first two don't deliver to EVERY address, the usps has been picking up their slack for a long time in that regard. So even if someone pays extra for ups/FedEx, and they live, say, off the beaten path, ups/FedEx will give it to usps to handle. This is in addition to those aforementioned ups surepost parcels.
