What is the difference between "help" and "help me out"? "out" seems means "until the end, completely", so does "help out" mean you will help someone till the problem is completely resolved?
M: Well, I saw a computer on sale yesterday and I really want to buy it.
M:The problem is I'm $100 short until the end of the month, and I'm afraid it won't be available until then.
M: Oh, please help me out.
