I'm new here, although I have tons of selling experience on eBay, Blowout, Beckett, Net54 and other sites. However, I've got a Must Send First label. And I understand if I'm doing a trade, I'd need to send first. But is that the case in a buy/sell transaction where I'm the seller? That doesn't make any sense whatsoever. So I could send the cards to the buyer, and he could block me and never pay or claim he never got them and get to keep the cards for free. Something doesn't sound right. Please help me. Thanks.
