Thank you for your question, "How do I motivate affiliates who are discouraged by the world economy's impact on the costs of products at Tripleclicks?"
I believe that the best way to motivate these affiliates is to encourage them to support "our store", Tripleclicks, by making their necessary purchases through a local ECA. This is a win/ win situation because they are increasing earnings at Tripleclicks and supporting the local economy.
