There's 2 places, one's the product list (depending on which setup you use it could be one of 2 or more files but you may want to change all the files in case you switch looks later on) and then there is the product details file. The option mentioned is to prevent it from updating the percent each time which is somewhat useful for variants. Open up the console and see which file is being used and you should find the TPL (they should all start with product*) == OR == you can search through your entire directory for "discount", "save_percent", and "$lng.lbl_save_price". Whichever seems to be more convenient.
