I decided to give it a go !   Good for you . What items did you bid on ?   A DENY shirt and one of Serena Williams ' used tennis rackets !   Your idol ! Wow ! You're even better at finding stuff than me !   Yep . I placed a bid for the shirt . The minimum was ten so I bet fifty !   That's not how this game works .   Well , there was a sign that said “ Buy now for seventy . ”
