ok, but how to understand that :
"The cost of a 30-Day Membership may be credited within 60 days of expiration toward the cost of an annual or three-year* membership."
and finally there is a * with explanation:
"*To take advantage of this offer, the annual or three-year membership must be purchased in person at any Delta Sky Club location. This offer is not available for purchase online. This offer is not retroactive and cannot be combined with any other offer, promotion, discount or frequent flyer program Award."
....so that is a kind of combined offer ? I have to order annual or 3 years as well ?
