Lots of things cause boxes to be returned. Here in FL the top one is dry ice shipping out (we seem to have a ton of it shipping out of Orlando). The box could have been damaged also, or gotten wet and needed to be replaced.
If you click on my swap page in my signature it takes you to our Member Page (thats what BYC calls them) and you can click create a new page there.
USPS wouldnt return a box based on predicted or possible weather 9see above for two reasons it could have been returned). Hope you hear back today on whats going on.
ALSO................ just thought of this.............They could have hit the wrong update as they scanned the tag, those hand hald scanners dont leave much room for error
what hub did the box go through? Orlando, or another spot in FL?
