I believe the $50 off $100 is apparel and accessories as well. At least from the picture of the Bubba Watson one that came in the mail.Not to pour salt on the wound of those who have been neglected, but I just got a little $50 off your purchase of $100 in store or online, and $20 off accessory purchase of $50.
Doesn't seem to have restrictions, so should combine with any discounted items. That's actually... not terrible!
