Discount Coding In Event Hub

Hi Team! 

It'd be great if we could offer promo/discount codes within Event Hub, so that we can push this out for special offers. A good example of this is a VIP event we have coming up where selected customers are going to be offered a % discount on drinks, and it would be lovely if they could have done this via Event Hub before they arrive. 

In addition, it would be a great way of driving additional sales on certain shows (get 10% off if you preorder your drinks on x event with x code). 

Thanks!
