Yes, miles per dollar from an authorised purchase is in addition to your credit card miles per dollar.
I believe this is discussed more thoroughly in the proper thread,
AAdvantage E-Shopping / Cartera Questions / Discussion / Vendors (consolidated), but I believe you must sign in and follow the link or risk earning no miles other than the credit card miles. And that thread discusses the lengths of time before miles "hit" as well as other experiences people have had with the provider, Cartera.
Searching thread titles, results in threads, for keyword
eshopping, reveals some threads as well.

-(unrelated) This could probably go in the CC thread as well, but, I'll ask here as well: How long after purchases go on your statement do miles get calculated and added to your AAdvantage account?
Thanks everyone.
