I think if you are not wearing it that much, then yes, you should put it on ebay. I sold several items on ebay, and even it is not as much as I hoped for, I see it this way: is it better to have a $1000 bag sitting in my closet, catching dust, or $500 on my bank account to buy my next true love?
OMG, I have the same dilemma myself, I have few purses out there and am thinking every day 3-4 times whether to stop the auction or not!!! Killing ! I do not carry them, but I am really sorry to lose them....I so understand
