Hello, I am Ukrainian, so sorry for my English.

When a customer go through checkout process he can see my product tax on Step 2, but I don't want him to see my charge... Is there any way to override displaying my tax?
I just want him to see Product price (with my tax already included), Tax for shipping and Total.

I think there is something I should do in \classes\order_total.php , but I have no idea how to change this file.
I think I should do something with output() and process() functions, but I don't know what to do.

I will be glad for any help.

Thanks
