Yep, this is one of the oldest scams on eBay, the seller opens an account, sells a high value popular item that doesn't exist and usually tries to get you to pay via Bank Transfer (outside of PayPal). They get the money, close their accounts and you never get your item.
A friend of mine won a ''brand new Iphone 7'' last week on eBay from a guy with 0% feedback. The seller said he didn't have PayPal and wanted a Bank Transfer....I checked the serial number posted in the listing and it turns out it was a FAKE one.
You could also do the same with brand new kites, ask for the serial number and see if it checks out.
The most frustrating bit is eBay won't shut down these auctions even if many users report it. There is basically no way for eBay to prove this is a fake auction, even though it's pretty obvious.
Always pay via PayPal so you get buyer protection, even if you fall for scam like this and pay via PayPal, you'll get a full refund.
BTW this eBay seller has 3 of these kites for sale and guess what, people will bid on them and the scam might actually work
