Need Help With Amazon Prime!?

[Tony]

So I clicked the sign up button when I was about to order some stuff and I thought I was going to have to fill out something but it just instantly joined me! I'm not even sure if this is the free trial, see it didn't say trial but it says I'll be charged next year today, so what? Did I pay 79 today? Or do i have amazon prime free for a year? So far amazon has taken 1 dollar and that's it. I have no idea what's going on

The $1 charge is just to verify your credit card. If you cancel within 30 days they will not charge you anything and you will not have prime instant video or free 2-day ship
