I've had pretty good success signing up as an Amazon seller to get rid of a few things I don't need anymore. My only annoyance is them massively under quoting on shipping costs, meaning you really have to do those calculations yourself and then price it in. This bit really irritates me as they'll sell you shipping from their seller portal, and even there it's massively more expensive than the price their quoting the customer for shipping.
