Welcome to TFP. As far as I know, at this point there isn't any Clorox bleach product that doesn't include "Cloromax", which are polymers intended to protect fabrics from breakdown in the laundry. This is not something you want in your pool.
If you need liquid chlorine, Walmart usually has the best deal vs Home Depot on their Pool Essentials brand. $5.75/gal or so. You can also usually source liquid chlorine from local pool stores where they sell them in 2.5gal "carboys".
