Try Google Pay and we’ll both get a $10 Google Play credit after your first purchase.
Use my code GAG57V2K: https://g.co/paypromo/GAG57V2K
Also, if you join before may 14, all new users who make 5 purchases in their first 30 days, will receive another $10 Google Play giftcard!
I currently have my paypal credit line defaulted to my Google Pay for the most secure and convenience payment method.
You can add as many debit/credit cards you would like to use via the app at checkout.
