Hi, You probably need to use javascript to make the total price auto-update when you check or uncheck each box. Check out jQuery if you haven't.
Once you have that, then, yes, you'll want to re-calculate the price in django to be sure it's correct. You could create an Order or Cart model that stores which (or how many of each) items have been select, and maybe the total price too.
