Payment processing for tobacco site?

wordpress does not have its own payment processing, it uses whatever one you tell it to use.

how do u currently process CC?
Do you have your own merchant account?

some people use paypal
verify with paypal they can take payments from sales of tobacco.

ouch. then u will need to find a merchant that does. contact visa directly, or maybe your bank.
