Agreed. That is why i list them on eBay for more at the same time. However, I am surprised how often the parts sell on eBay for a much higher price than they sell on MUD for.
I hope you get your asking price but that move was pretty lame indeed. I often list stuff on here for a certain price and list on eBay for a higher price due to eBay fees, logistics, idiot buyers, etc. I would say in the future, just do your research before posting so you don't get any backlash...
