I was at Dollar General today and saw a huge sign hanging in the window.
It said "Paypal now accepted"
I asked the cashier how does that work. His reply was, "I don't know, you want to try"
I said sure so I pushed the paypal option and it brings you to a screen to where you can then enter the mobile number or card number associated with your account.
Since I have no idea what is associated with my account I had to cancel the option and pay differently
But you can learn more about the PayPal option on Dollar General site.
