They dropped the Amazon cards this month to $3 for 3 pours - from $5 for 5 pours, but wanted to give a heads up at least it's a few extra bucks while out doing burger shops
That's what it is for the free style machines. When you go in you'll see a QR code in the bottom right of the freestyle machine. Scan it in the app and pour, then you'll get the credit. You only get credit for 1 pour every 24 hours.
If only the app would work. I was lucky if I got credit for 1/3 of the pours. I did a forced update and now even after multiple reinstalls, it forces closes upon opening. Great idea, poor experience.
