Disregard. The little cart on the side when you add it still showed $57 but if you click view cart from there you get the $8 coupon applied and it drops in price.
Finally going to upgrade from BI4 to BI5...wish me luck!
Looks like it is an automatically-applied coupon code blackfriday21 and you won't see it until you are on a page that calculates total using the coupon code.
