If i buy the 12 person pack on groupon, do Each person have to purchase their own 500 paintballs or can they be shared?

After purchasing a groupon every player must still buy a minimum purchase of $30 which includes 500 paintballs and unlimited air.

I'm not sure if they can be shared. It would be good to give them a call. We had a few bags left over so we gave them to a group that had just come as we were leaving. We wished we had not bought for everyone. It also depends on how active you want to be though.
