I found an eBay auction for a blender.
The price is too good to be true, but I bit anyways.
PLEASE NOTE: It might be a scam!
But they do accept PayPal. 
Seller has been an eBay member since 2004, but has zero feedback from anyone.
Seller has feedback from one seller.
...
I don't normally buy from eBay sellers with such little feedback, but I really want this blender and it normally sells for a lot more than $20.
Not True! Seller has one feedback from over a year ago, from 守信 很好 who is no longer a registered user. :person_facepalming:
The single feedback is from a seller, not a buyer.
Feedback is from 227346117@deleted.
Feedback is "守信 很好", which means "Good word."
No one said differently. 
I wouldn’t sweet it too much RC. Lots of people have ordered from really under priced sure looking scammers before, and were amazed when the product showed up.
The seller may have gotten a deal and want to clear them out. The product may be a little warm, but as long as it blends.
Pretty sure that means ‘trustworthy, very good’
