Sure, I might get more miles using a different card - shopping at OnePass with a OnePass MC will double up your miles - but getting a combination of both isn't too shabby.
Hypothetical MacBook = $2000
Bought through United Mileage Plus Shopping with Starwood AmEx:
2000 SPG points (2500 after transfer bonus) -and-
4000 Mileage Plus miles (Apple is 2X at United's portal)
Or am I wrong here?
I don't see any reason why you wouldn't earn miles with both since they are 2 separate programs so you could earn 2,000 SPG points and 4,000 Mileage Plus with that purchase.
