I sold a figure to this guy last week and he hasn't paid. He has high 100% feedback, and I just checked him out on goofbay and he's spent over £17,000 on Ebay in the last 30 days!
Mostly Dungeons and Dragons stuff but a few other MOCs too. So based on past history it looks like he'll come through, just worried by the lack of communication and huge spending spree!
