Just think of this. If you sell it whole, It's gone with one trip to the post office, end of story. Pat it and you'll spend ages listing everythig, You have to break it down, Then you have to collect all the payments, All those trips to the Posties and then your left with parts no-one wants, So that is where all the profit will be lost.

Another thing is that people that charge outrageous postage DON'T sell their Items. A good enticement is to suggest a price at which shippng will become free. A trick I used to great effect.
