Fuck that, I heard they never, ever take returns on anything ever. Never.
Unfortunately for you the current economic state will probably send folks running when they see your asking price, even though the value is great, people are being forced into carefully managing every aspect of their spending.
Even though the likelihood of selling these items privately is highly unlikely, only being eclipsed by the utter hopelessness of trying to get a return on these items, I would like to step in and play the proverbial White Knight and offer you $150.00. Which you can promptly spend, as opposed to wasting all of your time.
