I don't think they do, as I've never seen anything like that advertised. If you're looking for discounts, I suggest a drive to the stores just over the border into California, their prices are significantly lower, as the one area where California has lower taxes is on liquor.
Google guides are here to help you with our experience shopping at local merchants. For example is there handicap parking available or another example would be the helpfulness or attitudes of the employees at the store. A Google guide such as myself would have no way of knowing about any promotional activities they have since we do not work for the store. Perhaps you could call the store.
