it是指代 buy them on credit
make it adj to do sth ,it指代的是不定式部分

典型结构，it不指代任何东西

THE ONLY PRONOUNS ON THE GMAT THAT DON'T HAVE TO STANDFOR NOUNS:
It + description+ that +complete sentence (independent clause)
It + description+ to +verb (infinitive)
It + (TOBE verb) + NOUN + that/who + verb

these "it"s DO NOT have to stand for nouns.
ALL other gmat pronouns must stand for nouns.

FIRST TYPE

It + is obvious + that Medellín will beat Nacional in Wednesday’s game.



It+ has been said + that the moon is made of green cheese.

Johnny found it + counterintuitive + that the GMAT tests exceptions to rules just as often as ittests the rules themselves.

SECOND TYPE

It + is often difficult + to distinguish between a past-tense verb and a pastparticiple.

The rain made it + quite challenging + to drive on the freeway.

THIRD TYPE

It + was my own brother + who committed the crime.


Example: OG12 Question 57

后面的不定式？

panbangzhu

No......
不能理解为指代后面的不定式
....made it difficult to do ...   假如你认为这个it指代后面的"to do"的话，
I found it difficult to apply grammatical principles to a SC problem and to reach the correct answer.
这句话里面it难道该改成them? 因为后面to apply and to reach是两件事情啊！
可是事实上，这个it不能改成them，必须就是it。

所以说，这问题的正解，就是我前面贴的Ron的解释：固定结构第二种情形，此处it不指代任何东西
