All sales are binding!
When a 'Bid' and 'Ask' match, the trade is confirmed and no longer can be canceled. The integrity of the marketplace depends on it!
But for real, if the seller does not ship within 2 business days, or, the seller fails verification, we can refund you and cancel the trade.
The good news is that StockX is a live marketplace. Once you receive the shoes, you can always resell them on StockX.
