Maybe someone could call Customs to see if this is legit?
Or even.... I don't know how to do it, but there's a way to search ended auctions on eBay. See if there were in fact a bunch of uniforms purchased?
If this is just fabricated, a bunch of poor UPS teamsters are going to get pretty tired of showing their ID.
It seems to me that terrorists buying stuff on eBay- who regularly turns over account information to the government- wouldn't be the kind of terrorists mentally capable of constructing some sort of explosive.
Either way, thanks for the heads up. Better safe than sorry, right?
