What city are you in? Why on earth would anyone buy something used at a higher price than new? I kind of doubt your claim...unless of course the price you paid new, was some kind of inside deal that was lower than the average street price.
I'm slightly above break even on buying and selling used lenses and camera bodies. I've also sold two kit lenses for a nice "profit" over incremental price paid for a kit. I sold on eBay until their fees got too high, now use Craigs List almost exclusively. We live in a small town, but only an hour or two from several large midwestern US cities. As Neuro pointed out, the key is not being in a hurry to sell and waiting until you get your price.
Well, I wasn't in a hurry for selling the telescope, obviously...it took 3 years and I still had to let it go under the price I wanted. Obviously it was not in demand, etc. I should have just paid the $15 and put it on astromart, I guess.
I don't have the time or desire to spend to try to buy low and sell high, on used camera items, lenses, etc. I would rather flush all my money down the stock market toilet...it takes less time, and is more fun if I ever do make a profit.
Anyway, these are some fine Fujinon 12x60 HB roof prism binoculars I'm trying to sell, originally retailed for ~$800. They're made in Japan. I got them new from Eagle Optics for $299 a year ago, and am willing to take a slight loss on that. If you know anyone who likes binoculars, please send them my way.
Basically I went nuts in 2012, and spent too much on 3 pairs of binoculars (didn't buy any camera stuff that year). These are the pair I use the least often, but they work fantastically...have a nice wide apparent FOV, excellent in low light...a bit heavy but easily hand-holdable for a while...very steady view, good balance...come with carrying case and solid cast aluminum tripod mount, which I've used on a monopod lately. Handholding, I can easily follow nearby ducks in flight as they passed low overhead, etc.
