if you have time, you might consider e-bay.
I have had people balk at even paying the shipping for free stuff
If you are considering selling by mail - buy a postage scAle - you can get one fairly reasonably through USPS - do not short yourself on recoveriNg shipping costs.
If people moan at shipping costs - so be it. It costs most people something to go to a srore to shop.
Also, Do not ever short a customer. 35 inches is not a yard. Give accurate descriptions.
