No more AMEX points on gift card purchases according to doctorofcredit.com
Gift cards are now in excluded from points earning. A bummer because a couple of times a year, my local supermarket sells gift cards for their market (Gelson's) at a discount, and I usually buy $1k worth.
When I checked how my last purchase of gift cards show on the statement, looked the same as regular purchases, But that was in April, maybe they have updated the coding.
