I've sold a few items over the years. I probably have more that I could get rid of too.
I've used both ebay and the forum. Ebay now requires you to give too much personal financial info to be a seller IMHO. My wife was selling a lot of household items until they changed the rules. Too bad because the house was getting cleaned out.
Any future sales will be listed here. As to timing? I don't think it will make a huge difference in $$$$.
