Google Play - Free $1 Credit Towards an App or Game over $1

Google Play are offering a huge $1 free for purchases over $1 in there store. Useless to me but thought some might benefit from this deal.
* Exactly the same as in Decembers only half the amount. https://www.ozbargain.com.au/node/427107

Might also be worth noting that Google is still running the promotion for free $10 credit when you use the Google Pay method for the first 5 times.https://pay.google.com/intl/en_au/about/promotions/

Please check your Google Play store account link under 'Notifications' to see if you were gifted.
