What island are you living on? If you are in Santiago, you can post on the Capeverdean Facebook groups and if you offer reasonable prices, you can sell quickly. But this is how you sell inexpensive used items to the locals.
If your items are expensive, higher quality, then this Facebook group approach will not work well.
