Got the same offer, but not on all of my cards which suggests it is targeted.

UPDATE: Have ordered a case of the Mumm. With shopback, WISH card plus the 30,000 bonus points I make this to be around $19 a bottle.
UPDATE 2: Shopback has tracked as $0. Will have to follow this up in a few days if it doesn't change.
