Yeah, good money-saving tricks are the ones where you only spend a lot of time thinking once, and that helps you switch from one type of auto-pilot to another type of auto-pilot. If you have to think every time, then you pay with your time, and you quickly run out of available time.
For example, if you notice that X is equivalent to Y and costs less, it may take some time to notice, but afterwards buying Y is just as simple as buying X, once you develop the new habit. Or if there are two shops in the same distance, and you spend some time researching which one sells more cheaply the stuff you usually buy. (Or a more distant shop, that is so much cheaper that you can afford to pay for having the stuff delivered to your home, and still save money.)
