I think that is probably what happened. Something like that, anyway. I advised her to just return the package. Tell them that it was refused and let Amazon try to refund the money. Amazon had the drone on sale for $400.00.
I have heard of other people having this happen, and in one case, two other accounts had that person's home address on their list of shipping addresses.
it is a scam, and they may try sending minor things before a major purchase to setup purchase histories to an address, or as the other person noted, order big items on a fraudulant credit card and intercept the package at that address
