Diamond Perks

What's the point of having perks when the only ones that are really anything more than a contest entry,  an activity pack, or a percentage off of something like Universal Studios is gone 15 mins after they drop? I've been a customer for over 20 years and I can barely use any of these so-called perks. Go back to the way it was before you manufactured scarcity. I have notifications on but they often don't push out until they're already gone. #1, why can't you send a text out when they drop and #2, can we opt out and save some money? It just feels like the whole rewards thing is pretty disappointing.
