Hints on how to sell on A'gon?

there's a lot of good advice above. It's hard to disagree with any of it. I'll add some of my hot buttons.

1) provide a succinct and FACTUAL description. Especially describe the condition, age, and amount of usage/wear.
2) maybe provide a little bit about the features especially if the item isn't a well known. (eg, "tube preamp with 6 line level inputs, mm phono, remote control")
3) Include links to relevant internet info (ie Mfg website)
4) Don't bother with lengthy sales pitches, and don't make me read and essay on what a wonderful piece of gear it is. Instead, if you want to help, include a link to sales material and/or consumer reviews.
5) I don't generally care about why you're selling, unless it affects how motivated you are. If I become concerned there isn't total honesty, I may inquire about the reason for sale, but at that point I'm probably getting ready to move on.
6) Be realistic about your price.
7) knock off the knuckle head stuff like "if you're reading this you already know . . .".

I'm not saying you have to do all of these things, but IMO it improves your chances of selling.

Elizabeth makes a good point about packing. In every case that I received items that were damaged in shipment, the sellers (most of who had excellent feedback and lots if it) said it was all the shippers fault. That's BS most of the time. Packages get handled and dropped - that's a given, but if the items were packaged with the care Elizabeth describes, using boxes suited to the size/weight, it will eliminate 90% of the damage in shipment. Furthermore, the extra care required is a lot easier than dealing with claims and returns.
