Selling a Gas dryer....what Should Be My Asking Price??

depends on the brand. What did you buy it for? I would say you should expect to get 1/3 to 1/2 of the original price. so if it was originally $500.00 then you should expect to get paid anywhere from $165-$250. However that should NOT be the asking price. If you want $250, then ask for $275. People will negociate the price.
Dont forget to put that puppy on Craigslist. Appliances and work out equipment sell like crazy off there. I bought alot of my replacement appliances from C/L because I know I wont be in my house for more than another year and didnt want to spend a brand new price but didnt want JUNK for cheap either.

Definitely check Craigslist before deciding on a price. And then post on Craigslist as well with a picture. YOu never know how far someone might drive to get a pre-owned appliance.

I just looked and similar items in our area here in Western PA are going for $150-$175.

Scan your local classified ads to see what people are asking. You could also take into consideration what you paid or what a model with the same features sells for today would be a good place to start as well.

I'm just wondering if a dryer will be harder to sell since they seem to far outlast washers so not too many people may be looking for just a dryer. Hopefully that won't be the case!
