Hello, I wanted to buy some Robux but I've never bought those before so I don't know how it works.

I had some money on my Amazon account so I was looking if I could buy some there. I could only find game cards but I don't understand what they do. They only tell how much they cost in dollars but how much do you get in Robux? Or what are those game cards?

And is there any easier way to immediately get Robux instead of waiting till this card ships using Amazon money?
