I have a question for those who've participated w/ Bank Direct.

On their CD page https://www.bankdirect.com/products/cdmileage.aspx, it states:

* Earn 1000 miles for every $1000.00 spent on a two-year Mileage CD
* Earn 500 miles for every $1000.00 spent on a one-year Mileage CD
* Earn 250 miles for every $1000.00 spent on a 6-month Mileage CD

Is that xxx miles every month or within that period? I have about $200k I am looking to put in there, so the 1 yr CD would make good sense if I were to collect 500 miles per $1k every month equalling 1.2m miles at the end of the year.
