You won’t get the 500sb because thr total purchase needs to be 50 and the rewards certificate is technically a coupon. So you’d need to spend 60 total to get the 500sb.If you're unsure that's okay, I'm simply asking if anyone has posted this scenario before and what their out come was. Otherwise, I'll try this myself and report back. That way we have a definitive answer. I'll also include photos for verification if that helps out this community.
