How did you guys make your first sale?
I posted a for sale ad in the marketplace.
Pictures and details help, but for the most part, price seems to be the most important part to most. Price it attractively, and it will sell quickly.
Generally, the market will determine the price, regardless of the seller's experience.
Price it too high, and it can linger for months, or years even.
Price too low, and it will be sold within hours, but you may short-change yourself.
Price it right, and it should be sold within a month.
