Not sure if there is a better place to put this, but since I posted it here originally, here goes.
Ordered some used Bridgestone balls from Woot.com and they sent me the wrong ones. I ordered B330's, they sent E-series. Contacted them and they offered to do a refund right away, but they couldn't do an exchange until the upcoming "Woot-off" was over. So I waited and checked in again and they are sending the correct balls and told me to keep the mistake dozen too. Pretty solid customer service by the good folks at Woot!
