Ryan have you called any of your local pool stores to see if they have liquid chlorine? Most of the times Pool stores have 12% chlorine. You do have to pay a deposit on their jugs but in my case it is cheaper and easier than Walmart. You will need to think about how easy it is to get to on a weekly bases as well.
Just something to help save you some money. Your math does sound about right.
