Instant discount for add on cards?

Should show separately in addon's phone app...

brother, just for differentiating you from the actual primary card holder, different nomenclature adopted as add on, rest all things same to same in terms of discount offers. Whereas for monthly reward points cap, it will be collective means no additional enhancement in the monthly cap even if you take multiple add on cards. But for cash back, it depends on offer, some times they calculate collectively sometimes not. Since your question is about discount, you will get on each and every add on card independently.
