Medicaid Application Session 8 retro - CRITICAL: Never batch-fetch Amazon invoice pages with Promise.all. Parallel fetches cause data-shifting where order IDs get mapped to wrong invoice responses. Always fetch sequentially with 500-600ms delays. This silently corrupted 29 PDFs before being caught. Amazon invoice URL: amazon.com/gp/css/summary/print.html?orderID=ORDER_ID. Order details URL: amazon.com/gp/your-account/order-details?orderID=ORDER_ID. Amazon order search on Your Orders page is completely broken (ignores search terms).
