Selling off unused items

I decided to follow one of my own advices listed in my earlier post, 7 debtly sins. The advice was not to waste anything, where I defined even not using bought items as a type of wastage. Many unused items in my apartment were collecting dust, while credit cards used for their purchase are collecting interests. As described in earlier post (see Declutter Your Way Out of Debt), I just sold some of my barely used videogames, PS3 and Wii. For mailing them, I used my old first class stamps (37 and 39 cents stamps). After all, I shouldn't waste anything, including old unused stamps.  

PS. Also before buying a box to mail your things, check local stores for free throw-away boxes.
