Oopbuy's published help centre describes a linear agent workflow: submit a supported product link, pay for the goods, wait for the seller to deliver to the warehouse, review the warehouse inspection, then create a waybill for international dispatch. The platform publishes a no-separate-agent-commission model, a customs declaration reference that is generally CNY 8, and separate domestic and international freight. It documents practical payment choices — PayPal, international cards, Wise and Klarna — and a storage policy of 90 normal days, 30 days for abnormal packages and CNY 10 per additional 30 days after expiry. For a spreadsheet-led buyer, the useful discipline is preserving each handoff as its own column: source CNY price, the Oopbuy USD display, domestic freight, customs reference, payment charge, QC decision and the live shipping quote, each stamped with a date.
