Also just had points disappear from the Rapid Rewards portal (and my RR account) for a gift card purchase in May.

Also had AA miles clawed back from the AA portal for 3x purchases of actual items at Sears. I may have used coupons but only Sears ones that were in my account which never seemed to hurt anything in the past.

Obviously with the GCs you can't use coupons so that doesn't even make sense as a reason.
