Never was aware of the rule, but it does make sense. Those who need to prove(through lower rankings) should step up and have to handle their end of the transaction first.
If the transaction is a purchase, or involves money, money must exchange first regardless of ranking. Even if a trade+money, the money should go first. In the case of someone with trade item AND money, they should ship first.
Stuff like this makes me just want to continue to avoid BST. I know there’s plenty of honest sellers, but I’m just not up for “playing games”. I’d rather just do the retail/store route. It’s shame, I might be able to get a really nice yoyo through BST as I look for a high-end metal for purchase in October. Yes, purchase. I send money, and then the seller would send merchandise.
