If I see something I like, I ...
a. Try to talk myself out of it because I often regret buying stuff afterward.
b. Shop around to see if other stores have the same thing for less.
c. Buy it -- it's not worth the time to come back later and it might be gone by then
Call my friends to see what they would do.
===================================
这是原文,我想知道.c选择中it might be gone by then是什么用法,怎么翻译,might为什么不能用may?
还有would为什么不能用will
