I think that is a little harsh. I use a site called gixen to bid on my ebay items for me. I put in my maximum bid (30 in this case) an it does the rest for me. I dont see how someone listing an item with no reserve and me winning it for a low price equates to me trying to rip someone off.
I am someone who will honor the trade even if it is making a loss cause it is my own mistake for not setting a reserve price or whatever.. Let see what happen ..... Good luck ..
I did the same for a "gold" coin cos I was curious to see how terrible it was. It arrived, I had a good laugh, lodged a paypal dispute. All it cost me was a few bucks to send it back to the scammer, the rest got refunded.
