It's sticker season once again and if you're collecting the 2020 Starbucks Planner, it's very similar to last year's rules. First, you need to opt-in to the promo on your Starbucks app then you'll need to buy 18 Tall drinks.
The cheapest drink you can purchase is a Tall Brewed Coffee at PHP 110.00 (5 calories) each which means you would be shelling out PHP 1,980 to collect one planner and you would also be consuming a total of 90 calories.
To produce a standard coffee cup, one would emit about 0.112 Kg of CO2which means 18 cups will contribute about 2.02 Kg of CO2 emissions. To help the environment, bring your own cup and you also get to save PHP 5.00 per drink.
