Hi,
I just placed my 1st order last night. When you go
through the checkout process, there is a "Comments" box. In that box you type in your options -- manual or auto battery, color of battery, color of case (if ordering the PCC). If you're ordering the Ultimate kit, there are probably more options. Also, if there are carts included with the kit, you need to place your flavor and strength in the Comments box as well.
Hope this helps.
BTW, if you mess up, just email Steve. He's really fast at responding to his emails (I know because I had to email him last night). Just click the "Contact Us" link about half-way down the page on the left.
