At STACK, we love giving our members exclusive offers and/or deals for things we use on a daily basis. Unfortunately, offers that were available in the past cannot be retroactively added to accounts after it has expired.
To see which offers are available to you, log into your STACK App. Afterwards, you'll see all the offers that are currently available to you in the offer section underneath the WORLD and YOU tabs.
Log back into your STACK app regularly to see when new offers become available to you
