When customers submit a Bid below the current lowest Ask, they will be able to determine how many days the bid is live for - 1, 3, 7, 14, 30, or 60. Customers will always receive an email from StockX when their bid is about to expire to see if they would like to extend it. Additionally, customers are free to adjust the price of their Bid or cancel it entirely at any point before it matches with an Ask.
