"After launching an initial March campaign that offered anyone with a valid COVID-19 vaccination card one free Original Glazed doughnut every day through the end of 2021, the chain doubled down when uptake lagged. Starting August 30 through September 5, vaccinated customers (with at least one dose) can receive two free doughnuts per day: one Original Glazed and one heart-shaped Original Glazed Heart, the latter touted as an “innovation rarity,” under a temporary “Show Your Heart” promotion meant to boost vaccinations as infection rates rise. There is no comparable offer for the unvaccinated." - Rachel Sugar
