The Mega-Sale Playbook

Indonesia’s year-end mega-sale season can deliver record-breaking GMV, but rising marketplace fees, stacked discounts, fulfilment costs, returns and operational failures can quietly erase the margin behind it. The Mega-Sale Playbook shows retailers how to look beyond headline sales and measure the true economics of 10.10, 11.11 and 12.12 using the Peak P&L. It explains the hidden “surge tax,” the growing challenge of owning marketplace customers, and how brands can turn one-time discount buyers into long-term, repeat customers.
