Coupon codes apply well to most everything (subscriptions, one-time products) but I funnel my customers to a "trial kit" first (using your awesome trial period functionality) and the coupon codes won't apply to it. So, it pretty much negates my ability to offer new customers any logical coupon code experience. :/ I'd love to be able to offer them "free shipping" (a coupon code equivalent to the shipping amount) but can't do it. Help!
