Here's the response from Topps that I received via email when I asked for clarity on "random". Of course, my question was not answered.

Hello Jeff,
As per the product description, sketch cards are randomly inserted. Obviously, the more you purchased, the better chances you have of receiving sketch card(s) but nothing is guaranteed. As alluded to prior, in the coming days the bonus orders for the sketch cards will start to process if you will be receiving them. Thank you again.
Best regards,
Jake

Thanks Jake. Help me understand "random". So are the odds the same for someone that bought 1 set vs someone that bought 20 sets?
Jeff
