10000 base points for $1000 spend
8000 bonus points for Gold
10000 bonus points for 2x points rate
10000 bonus points for the double points promotion
So a total of 38000 points.
Also note that you do not earn points on taxes, so if the cost is $900 plus $100 taxes, then points would be 9000 + 7200 + 9000 + 9000 = 35200.
