I guess you'll just have to take my word for it. I don't know what kind of proof there is. All I am saying is that I had all the concerns of all the posters here but took a chance. If there were a problem with the order, Paypal would have refunded me, a big hassle, but it turned out good. I was quite relieved when I got to inspect them and listen to them.
I also found out that all the contact info would not work. No working telephone number and no working links from the website for customer service. Only way to get a reply is through the email address supplied through PayPal.
Oh, by the way, The shipping box came from a Best Buy in Kentucky with a Best Buy invoice/packing slip for the amount of $159.00. I thought that was weird.
Here is my best guess what is going on.
Scammer sets up a fake store. When they get an order, they use a stolen credit card to ship the item to you from a legitimate retailer (Best Buy in this case, that is why you have the Best Buy receipt in the package). Scammer then pockets the original money, and word of mouth helps them get additional orders. At some point the system collapses, they take the money and run and use any credit card/PayPal info they have for their new fraud store, scam rinse and repeats.
Something like this happened to a pilot I was paired with who used a discount bulk disposable diaper internet service. The diapers he ordered and received were actually purchased with someone else’s stolen credit card. As far as he knew, he ordered diapers and they arrived as normal. A couple of months later the police showed up on his doorstep. It turned out the real account holder noticed a fraud charge on his statement, and get the police involved. It was easy to track as the statement had the legit retailer on the statement, and the retailer had this pilot's address as the receiver of the diapers bought with the stolen credit card.
The police said later his card info would probably be used to send diapers or unrelated merchandise to others. (This was a few years ago, I am fuzzy on the exact details of the story.)
First thing I would do is change any thing that you might have inadvertently given to the scammers. (PayPal password may have been intercepted by the web site, or any credit card info given to them for example.) I would also keep any info from the “discount” web site (emailed receipts, contact numbers, web addresses) in case the police knock on the door and think you committed fraud vs being a victim yourself.
