Well if you’re a resident of Illinois you can’t go to another state and buy a gun from a licensed dealer. You’d have to have it shipped to an FFL in your state. Since this rule is in effect then the FFL in Illinois wouldn’t sell it to you.

The only way you can go to another state and get a gun is if it’s a private sale.

It won’t. They’re just banking on you forgetting you signed up so they can charge your card.

But If there isn’t any money on the card then they can’t charge you. Think of it as signing up with a gift card in a way. However the times that I’ve done it I haven’t been able to use a card with $0 on it. I’ve always had to put at least $1 on it so the card can be verified.

Idk if I explained that well

tl;dr: No
