We can all agree that once a list is published, it should be irrevokable. That's poor. I disagree with the position that, should a property decide to change their mind, there's "nothing we can do."
I work for a major global manufacturer who does nearly all of our business through stores in YOUR neighborhoods and nearby malls. We offer CRM (consumer relationship marketing) options to each store that includes outbound postcard mailings and birthday cards, etc., to the store's consumer database. These are enrolled in contracts signed twice a year for 6 month timeframes. You can bet your bippee that we 100% require full compliance and non-reversal once the contracts have been signed and agreed to.
The ONLY way the agreement can be terminated is if the store CLOSES. Otherwise, once the offer is out there for the consumer to see, it is positively irreversable. To do otherwise is very poor IMO.
