So im on toribash like usual and im trying to buy tc but when i enter all my credit

and information all it says is that my card is invalid but i am sure it is not

because i have used it before within a month

Make sure your card can be used online. I suspect you're trying to use a debit card as a credit card, which will not work. Also make sure there are no restrictions from your bank. Ask them to find out what's wrong.

Im pretty sure it can be used online because i have used it before like i said online and i did check with my bank they didnt see anything wrong but i still cant buy tc
