I believe once an app is purchased you should do with it as you please. Like sell it to a friend. Put it in Ebay or the like. There should be app resale sites to facilitate such. I have bought apps, used them for a day and never touched them again. What are your thoughts. If you bought a lawnmower, used it for a day and didn't like it, it would not go in the shed till the end of times like your unwanted app purchases do. You would sell it.
