Is there any difference in "pass up something" and "pass up on something"? The expression used here is "pass up something", but the example in the Q&A is using "pass up on something", so I was curious.

These two expressions mean basically the same thing! You can use them interchangeably. Usually, however, "it's hard to pass up on" will be used more often. Ex: It's hard to pass up on a slice of cheesecake. Ex: It's hard to pass up a slice of cheesecake.
