Include more info - Price include shipping? If so lower 48 or what? Non-smoking home? OBO? no low ball offers? Link to your Heat? What payment methods do you take?
They all help you move your stuff. But as noted, price it the number one factor. If you are pricing it based on what the Ferengi on Ebay and used marketplaces charge, you done goofed. When I sell stuff, I do not consider what I paid for it. I got my use out of it already, so I price with that idea in mind. If you bought it on Black Friday or something and now you are selling it for NIB for that price or higher to recoup shipping, that is a different story. NIB for 10 percent or better discount v. what is going for at the moment is still a good deal imo.
The most confusing part is that this is ATOT baller land, and they act like they are hard up for cash when they sell the old stuff. WTF m8? Ballers don't sweat things like that, they shoot dollar bills out of a money gun at strippers. Remember that when you sell your stuff, and stop trying to get Ebay money without all the fees, you cheap bastages.
