When I find something I like I end up ordering it over and over again, never wanting to substitute. this solves two things, no decision needs to be made, and cost/benefit analysis of ordering something new says the risk of not getting something good is too high to chance so i'll just keep getting the same thing until i'm tired of it, because I know it is good. boring I know.
I tend to do that naturally, but in an effort to get more experiences in life, I try to always go for something new.
