Can I use a Promo Code with a Series?

When a Series is created, the pricing is set for the whole Series. A Promo Code that is applicable to an Open Play can be used on a League that is a Series, and the Promo Code will apply to the whole Series price.

Here is a brief video showing how the Series was $15 for Members and $30 for Non-members, and a Promo Code that offers a 50% discount.
