First you have to have a smartphone. An android or an iPhone will do.
Next you have to go to the Google Play Store or the Apple App Store and look for the Yellow Cab App.
Install the app. Tap on the 9 dots on the top left and then tap sign up.
Once you are signed up just tap on the coupons button and click on the coupon for the free ice cream!
That's it! Just present the app to the cashier when you order. And you also need to make sure that your order reaches the minimum of P500 pesos for you to get the free ice cream. ^_^
Another thing to note, make sure that the branch manager of the Yellow Cab you're claiming this freebie from has their code. It's a unique code that each manager has to enter to confirm that the ice cream is from that branch. When my friend and I tried to claim this freebie from the Yellow Cab near our office, the manager didn't have her code. I'm guessing she's a newly hired manager that's why she doesn't know what her code is. Anyway, she gave us 20% off the total bill instead of a free ice cream Which was even better!!
Hope you get your free ice cream soon! ^_^
