I can't remember where I read this, but I read a very similar sentiment: "If you can only afford $2 pizza on a regular basis, never buy a $20 pizza, because it will just ruin the $2 pizza for you."

Another aspect of this which doesn't depend on price, is when I get attached to some regional variety, and then I move. That's always a bit painful.

Or sometimes they just stop making it. Or they change the formulation!

Attachment is the root of suffering...
