I usually list stuff on the high side and expect offers as everyone likes to get a "deal". I will wait until I get a fair offer (hence Brioni that just sold for $275 took 3 months to sell). Had a few $200 offers in the first few days, but knew it was a $275-300 suit to the right person. I also factor in the number of view and watchers but typically after 3-4 weeks I;ll put it on 15-20% off sale for 5-7 days then when the sale is over I will mark it down to the sale price and start over in 3-4 weeks again. Some higher end items will just go on sale and stay put as I know what they will usually sell for. As said, it all comes down to how fast you want to sell it. As long as the price is close to FMV then its just a waiting game for the right person to come along who likes it and wants it. I would say most items sell within the first 7 days or take about 45 days on average to sell.
