Dermomama review for BuzzSubs: Spin Wheel Popup

I contacted the developer early this year and asked for TWO things which were never answered. #1- There SHOULD be also a customer name on the wheel, because if you only get the customer email and you want to send them and email who to greet them? with their email address? #2- The discounts, apply to ONLY ONE PRODUCT? or any quantity? Because i want to have a offers lets say 80% off. Does this mean the customer at this time of purchase can buy the whole stock at 80% off? But never heard anything back.
