As you did receive an item in the trade, this is not a scam. The closest it could be considered is a shark, however, the prices of genuine items tend to vary wildly depending on demand. However, you are welcome to report this on Mann Co Trading or AceFortress as both communities are handling our sharking reports for us at this time. Thank you.
