I made it for my father because he wanted a good navigation mao but it cost a lot of money. Thanks that exist Internet in our days because I found on https://yourmoneygeek.com/free-google-play-credit/ many ways how to get free Google Play credit. One thing saved me a lot that my father has a Samsung because if you register from Samsung devices you get 50$ on Google Play store. I also tried some new apps which gave me some points that I trade them in credit in the Google Play store.
Did any of you make a google play gift card as a gift to somebody?
