My wife ordered some shoes right before Christmas and a package showed up but inside was someone else's shoes and an invoice with the actual buyers contact info. The vendor wanted her to send it back, then wait for it to deliver and then call them again to get what she actually ordered.
Instead, we contacted the guy whose order she received, and wouldn't you know it he got my wife's order. So they just shipped what they had to one another and skipped Famous Footwear entirely. It cost them shipping between Oklahoma and Texas but they each had their stuff about 2 weeks earlier than they would have.
