I run a small e-commerce business, and over the past two years I've watched shipping costs eat up more of our margin than almost anything else. When I talk to other owners, we all seem to face the same dilemma: do we absorb the surcharges and risk losing profit, or pass them to customers and risk losing sales? I've tried both, and neither feels sustainable long-term. What are you doing to manage carrier rate increases and delivery surcharges without breaking your supply chain budget?
