Vinyl Flooring Without Underlayment?

I was lucky enough to acquire a large quantity of used Shaw vinyl flooring last year (the kind that snaps together), along with 3 brand new boxes of the same flooring. I am attempting to install this in my own house and have removed the old carpet, padding and staples and am preparing to actually begin laying flooring. The prevailig wisdom is to use underlayment which adds 30-50 cents/SF to the cost. If I don't use the underlayment what kind of problems am I really looking at?

Vinyl needs a smooth surface as it is very good at telegraphing imperfections in the floor below it.

You can try to make the floor smooth by using a cement based floor fill. Do not use the cheap gypsum based, they will crack over time and powder out.

I think I probably will just spring for the underlayment. I've got most of my carpet up and the floor it pretty flat so I think with a little more prep work and underlayment I'll be fine. Thanks.
