Pop Fizz Clink Promo Card (outlets only)

if the promotion is 60% off everything and then additional 20% off full price handbags (like they did for Presidents' Day weekend), are you able to then take another 30% off with the pop fizz clink promo? or does the 30% off just applies in place of the additional 20% off?

My understanding from another post is that they will apply two discounts, i.e. 60+20 or 60+30, but not three.
