Is it the same with the app? I have Starbucks app instead of the card. It's much more convenient and easier + I tend to lose the card 😂. The stars system there seems more difficult to get than in Indonesia. For me, to get free drinks it's usually 2-3 days of purchase since free drinks is about 100 stars and you get 1 stars for every 0,34$.
Yeah it's the same with the app since you just register the card to the app anyway... So even if you don't bring the card with you, you can still use the app :D It is very difficult, I never got a free drink even tho I already spent $200+ on it. :/ In Indonesia sounds easy haha
