Well, dang! Someone just sent me an offer (which I accepted). THANKS!
I checked my email and I did NOT get an email from COMC for this offer. I checked the junk folder and there was nothing in there either. It was in my Dashboard on COMC.
The best course of action would be for everybody keep sending me offers until COMC gets this sorted out. I'm willing to help them troubleshoot this problem, even if it means selling every single card I own.
