When people have the $20 for $20, or $10 for $10, etc. at U.S. dining locations on various branded cards, how long are these credits taking to register in Savings and/or post? I used the $10 credit for $10 on my Hilton card in mid-Feb and it hasn't registered, either by email, in savings or credited. The establishment where I spent (a local microbrewery) was shown on the map when I clicked the AmEx link to find eligible restaurants.
