Is the stuff you're selling more obscure?
I had 1-2 months of quiet for all my stuff but then I suddenly had an influx of serious offers and demand.
Sometimes taking the hit on ebay is just easier.
Personally, I find that most of classified threads are not good and realistic prices for used products and too much scalping is going on.
It also doesn't help that you have so many people drooling over clacks, bumping those threads with their envy and stupid GLWS and you also had to deal with a flood of inappropriate april fools jokes posts which hurt serious sellers.
I would help but noobs have to wait two months to post!
You can PM though.
