For just $199, I'll sell you my PDF explaining exactly how to do this well enough to make WAY more than only "some cents here and some cents there". Special limited time offer for HN readers, reduced from my normal price of $1,489!
P.S. Or get it free when buying my $499 "how to make money selling people how to make money guides" guide!
(/s. I generally think HN comments should avoid jokes unless they're genuinely really cleverly funny, which this comment isn't - I only justified it to myself by the fact that the sort of people selling these trashy guides are the same people doing what you're talking about, and I feel they deserve mockery and shaming.)
