When I have multiple various goals, I remove those related to them, off my tip menu. If users discover there’s a way to get that item cheaper, they absolutely will. But even if that item is the same amount on your tip menu as you have set for a goal, there’s just no point in having both. If you remove it from your tip menu, when you go back to add it the next day or so, as you start typing the amount in it will show it for you to select again. Like a saved drop down. At least mine does.
