아멕스 델타 플랫 델타구매 $100 크레딧

안녕하세요?
아멕스 델타 플랫 카드를 만들었는데 3개월 이내 델타에서 구매시 $100 크레딧 주는 내용에 대해 궁금증이 생겨서요. 최대 $100 statement credit이라는 마모님의 설명이 있는데, 이 게시판에서 2013년도의 글 중에 델타에서 $5만 구매하고도 $50 크레딧(델타 골드카드인 듯)을 다 받았다는 글을 봐서요.
이번 델타 플래티넘 카드도 델타 사이트에서 아무 금액이나(즉 델타 e기프트카드 $50 같은 것) 구매해도 $100 을 한번 들어온다는 것인가요? 아니면 쓰는만큼 크레딧이 들어오는 걸까요?

Offer terms를 카피해 붙여봅니다.
One statement credit for $100 will be issued to your Card account after a Delta purchase is charged to your Platinum Delta SkyMiles® Credit Card within your first 3 months of Card Membership. Purchases to meet the spend requirement include those made by both the Basic and Additional Card Members on the Card Account. Purchase must be made directly through Delta. A purchase may not qualify for the statement credit if it is submitted under a merchant code that has not been categorized as a Delta merchant code as of the date of the purchase(s). Credit will be issued as a Card Member statement credit approximately 8-12 weeks after your first Delta purchase. Additional Card Members on your account are not eligible for this offer. To receive the $100 statement credit, your Card account must be active, in good standing, and not in default at the time of fulfillment.

You can earn a $100 Statement Credit after you make a qualifying Delta purchase on your Card within your first 3 months of Card Membership starting from the date your account is approved. In rare instances, your period to make your first Delta purchase may be shorter than 3 months if there is a delay in receiving your Card. Also, purchases may fall outside of the 3 month period in some cases, such as a delay in merchants submitting transactions to us or if the purchase date differs from the date you made the transaction. (For example, if you buy goods online, the purchase date may be the date the goods are shipped). For questions regarding your Card account, please call the number on the back of your Card.
