Discount Code improvements for GoToTraining
1. It would be great to have an option to enter a date range or at least expiry date for discount codes associated with GoToTraining sessions. Examples of uses include: Early Bird Discounts, Flash Sales, Last Remaining Seats, 1 time promotions (ie: Free) 2. It would be great to have the option to specify the amount of times a discount code can be used (ie: 10 times or $1000 worth)
