The easy way around this problem is to be aware of the value of your time. If it takes you another ten minutes to save 1-2 dollars and it feels like a chore, then it's obviously a bad deal.
Of course, your time isn't always worth the same. You may find yourself on a Sunday morning with time to burn (or retired/unemployed), in which case you might as well look for a better deal as a matter of principle. It also may be the case that going out of your way is enjoyable for other reasons and doesn't feel like a chore.
It's all about being aware of how the price you pay for anything is composed of many variables (time, money, sacrifices, etc) whose relative values are constantly readjusting.
