In general Chase UR mall has been extra generous with bonus points IME, though I don't remember the particulars I remember getting points for the pre-coupon total when using a coupon (don't remember which merchant).
I actually dont think they are being nice about it - I think their system is a little messed up ... I had a few purchases that they didnt pick up.
I also got once pre-coupon points ... I just there are flaws in their system, for the same reason some times it works to pay with a different CC
I think we should make a list of the sites people used different CC to pay, and they got their points
