Q: What's the process of redeeming a coupon once I get it on my phone?
A: Once you get your coupon code, just show it to the merchant that offered you the code. It's best to let them know in advance, if i.e. you are going to a restaurant etc.
Q: what can I do if I don't receive my coupon even though my phone got validated?
A: Click on the send coupon again and repeat the process.
