Consider ease of resale as well

If you mainly view the trade as a step toward another sale, consider how easy the received item will be to convert into cash.

Two products with the same theoretical value may have:

• very different demand;
• different typical selling times;
• broader or narrower markets;
• different shipping costs;
• different dispute risks;
• different sensitivity to condition and originality.

If you already know you will immediately resell what you receive, its practical value to you may be lower than that of an item you actually want to use.
