I reported the listing to Ebay. They can sort it out.

By making an offer not through eBay, you open yourself up to getting scammed. When you make the purchase through eBay, there are money back guarantees and buyer protections in place. I would not recommend emailing and making a private sale in this manner.

The ad is no longer there.

Wow, so it was indeed a scam. Thanks for reporting it, CathieD!

EBay said this is an error page. Whatever that means!
