Maybe these little things have such low margins that it wouldn't be cost effective to pay me to return it, then have to sell it as an open box product and lose more money on it. Its probably just a drop in the bucket to them.
I doubt that the margins are that low. Probably just a customer service rep taking the easy way out. ("Pretend you never called us.") I'm surprised that they didn't just issue you a call tag for return shipping.
But there's still the larger question about _how_ it came to be shipped to you. I'd be a little concerned, and, to tell the truth, I'd want to know what happened.
Either:
It was ordered legitimately and sent to the wrong address. Amazon will most likely just send another one out to the original buyer at the right address. Not a problem for you.
- or -
As mentioned above, someone may have ordered it using a stolen credit card number and had planned on scooping it off your porch before you got to it. This is the one that I'd be worried about. Someone specifically said to themselves "That place looks ideal for my little fraudulent purchase." If this is the case, it could be a neighbor or someone living close by and they could just as easily scoop something that
you've ordered off of your porch.
