How should I price fans for sale?

Single Corsair fans sell for about $15 - $22, new, on Newegg. 140mm a little more.
I suggest about $5/fan.
But is the hassle of shipping etc. worth it for, say $25 total income?
If you don't have any spares hanging around I would save the 140 and one 120 in case one of your new fans
dies, then you will have a substitute 'til the replacement arrives.
The other two; post a note at the grocery store or on a college campus and sell em that way.
