Simplest Checkout

What is the simplest checkout? I keep getting the login and registration. Do they have to register? I don't want them to have to activate their account by going to their email.

Maybe this is not securely possible but I woiuld just like them to put in their address and shipping information and buy the product.

Thanks,
Toni

Activation is only required if you activate the user account activation option of the joomla user manager. Disable it and you won't have it.
