You may be on to something. Me and my wife both picked up SPG cards last month.
I met the $3k requirement on Sept 4th (no Serve loading), and the 30k bonus points have already posted. She did roughly $2k in legit spend and $1k in Serve loading. She met the spend requirement on Sept 2nd. She has not yet received the 30k bonus, even though her statement has closed and she has received Starpoints for the 2k in legit spend (as anticipated, she received no points for the Serve loading).
